‎ 1ere édition française, édition originale princeps, 1974 Contents, Chapitres : Table, préface de Jean Dieudonné (6 pages), xiv, Texte, 72 pages - Félix Klein : Considérations comparatives sur les recherches géométriques modernes - François Russo : Groupes et géométrie, la genèse du programme d'Erlangen de Félix Klein (conférence donnée au Palais de la Découverte le 4 mai 1968 - Felix Christian Klein (25 avril 1849 à Düsseldorf 22 juin 1925 à Göttingen) est un mathématicien allemand, connu pour ses travaux en théorie des groupes, en géométrie non euclidienne, et en analyse. Il a aussi énoncé le très influent programme d'Erlangen, qui ramène l'étude des différentes géométries à celle de leurs groupes de symétrie respectifs. - La synthèse de Klein de la géométrie comme étude des invariants sous un groupe de transformations donné, connue sous le nom de programme d'Erlangen (1872), influença profondément l'évolution de la géométrie et des mathématiques dans leur ensemble. Ce programme était le cours inaugural de Klein comme professeur à Erlangen. Il propose une vision unifiée de la géométrie. Klein décrit en détail comment les propriétés centrales d'une géométrie donnée se traduisent par l'action d'un groupe de transformations. Aujourd'hui, cette vision est devenue tellement banale dans l'esprit des mathématiciens qu'il est difficile de juger de son importance, d'apprécier sa nouveauté et de comprendre l'opposition à laquelle elle a dû faire face. (source : Wikipedia) - En 1872, à l'âge de 23 ans, Klein obtient une chaire à l'Université d'Erlangen9 grâce à l'aide providentielle de Clebsch, qui voit en lui l'un des futurs plus grands mathématiciens de son temps. Selon la coutume, il doit donner une conférence inaugurale. Il prépare un texte qui circule initialement entre un nombre restreint de lecteurs, sous le titre de Vergleichende Betrachtungen über neuere geometrische Forschungenn. Il s'agit du fameux Programme d'Erlangen dans lequel il propose un point de vue révolutionnaire sur la géométrie. Bien que ses qualités d'enseignant soient appréciées à Erlangen, il n'a au début que deux élèves dans sa classe. Dans un premier temps, le Programme d'Erlangen n'est pas bien accueilli, sans doute parce que le manuscrit n'a pas bénéficié d'une large diffusionn. Félix Klein ne reste que trois ans à Erlangen il n'a pas beaucoup d'élèves , mais a assez de temps à consacrer à la recherche. En 1872, Clebsch succombe à la diphtérie à l'âge de 39 ans. Klein s'occupe alors de la publication de la revue Mathematische Annalen responsabilité qu'il assumera presque jusqu'à la fin de sa vie et parvient à en faire la plus importante publication mathématique de l'époque, ce qui contribue à renforcer son aura scientifique à l'échelle internationale. En 1875, une nouvelle chaire lui est proposée à Munich (source : Wikipedia) couverture à peine jaunie sinon propre, intérieur frais et propre, signature de l'ancien propriétaire sur la page de titres, cela reste un bon exemplaire‎

‎Zum Mehrkörperproblem der Quantentheorie (+) Über Wellen und Korpuskeln in der Quantenmechanik. - [JORDAN-KLEIN MATRICES]‎

‎Berlin, Julius Springer, 1927. 8vo. Entire volume 45 of ""Zeitschrift für Physik"" bound in contemporary half cloth with gilt title to spine. Library stamp to title-page. Corners and lower capital bumped, hinges a bit weak. An overall fine and clean copy. Pp. 751-765"" 766-775. [Entire volume: VII, (1), 910 pp.].‎

‎First publication of Jordan and Klein's influential paper (the first mentioned) which contributed to the close connection between quantum fields and quantum statistics, today known as Jordan-Klein matrices. ""Born, Heisenberg, and Jordan had indicated, and Dirac had demonstrated, the close connection between quantum fields and quantum statistics. Second quantization guarantees that photons obey Bose-Einstein statistics. What about other particles which obey Bose-Einstein statistics? The year 1927 was not over before Jordan and Klein addressed this question [in the present paper]."" (Pais, Inward bound. p. 338). ""Jordan and Klein found that ""one can quantize just as well the non-relativistic Schroedinger equation. In honor of these contributions the matrices have been named Jordan-Klein matrices."" (ibid. p. 339). ""Convinced that the many-body problem in quantum mechanics can be stated correctly only in the context of quantized matter waves (""repeated"" or ""second"" quantization. as it was called later by Léon Rosenfeld), Jordan started working out his ideas together with Wolfgang Pauli. Oskar Klein, and Eugene Wigner. During his stay in Copenhagen in the summer 1927 Jordan established, together with Klein, the first nonrelativistic formalism of second quantization for a system of interacting Bose particles."" (DSB).The second paper, ""Über Wellen und Korpuskeln in der Quantenmechanik"", ""contained several other formal and mathematical generalizations, but its main practical value is that, in the newly established theory of the 'quantized wave field', the fluctuations in the Bose case now satisfied all requirements following from Einstein's light-quantum treatment of 1924 and 1925.""

‎Première traduction française, avec texte en latin en regard, due à François-Alexandre Aubert de la Chesnaye des Bois de cet ouvrage traitant des oursins publié pour la première fois en 1734 sous le titre latin Naturalis Disposito Echinodermatum et dû à Jacob Theodor Klein. François-Alexandre Aubert de la Chesnaye des Bois (1699-1784) est écrivain, généalogiste et compilateur français. La Chenaye des Bois est principalement connu pour ses publications sur la généalogie des familles nobles et notamment son Dictionnaire de la Noblesse. Jacob Theodor Klein (1685-1759) est zoologiste marin, naturaliste, juriste, botaniste allemand et membre de la Royal Society. Il possédait lun des plus riches cabinets d'histoire naturelle dEurope. Sa collection d'oursins, dont certaines parties sont conservées dans la collection zoologique d'État de Munich, est considérée comme une source précieuse de matériel scientifique pour les zoologistes et les paléontologues. Klein est connu notamment pour avoir bâti un système de classification se voulant être le rival de celui de Carl von Linné (1707-1778 ; naturaliste suédois) et pour avoir fondé le jardin botanique de Ogród Botaniczny w Oliwie à Gdansk. Il "avait des intérêts nombreux et variés en histoire naturelle en plus des oursins. Il développa un jardin botanique à Danzig, y fonda et dirigea une société de naturalistes, fit de vastes collections et publia environ deux douzaines de monographies, y compris des études sur les oiseaux, les poissons, les reptiles et les invertébrés autres que les oursins, en particulier les mollusques" (D.S.B.) Son traité précurseur sur les oursins, reconnu comme lun des principaux ouvrages sur le sujet jusquau XIXe siècle, résume les sentiments de lauteur sur les méthodes taxonomiques. Sa méthode est entièrement basée sur des caractéristiques externes, telles que le nombre et la position des membres et de la bouche et il s'oppose vigoureusement à toute méthode, y compris le système linnéen, basée sur des caractères non visibles extérieurement. Son ouvrage contient également une table générale dune méthode zoologique classifiant les animaux qui ont des pieds et ceux qui nen possèdent pas. Lillustration se compose dun attrayant portrait représentant Klein debout devant son cabinet d'histoire naturelle et de 28 planches gravées par Maisonneuve représentant diverses espèces doursins. Les 6 dernières planches sont gravées daprès les dessins originaux de Humblot doursins qui se trouvaient dans le cabinet de René-Antoine Ferchault de Réaumur (1683-1757 ; physicien, mathématicien, météorologue, naturaliste français et directeur de lAcadémie des Sciences). Bel exemplaire conservé dans sa reliure dépoque. 1 vol. 8vo (200 x 128 mm) bilingual Latin-French of : [3] ff. (false title, engraved portrait of the author, title with vignette); 233 pp. (including preface, tables, disclaimer, inconsequential pagination error); [3] pp. (including errata and bookseller's catalog); 28 off-text engravings. Endpapers. Contemporary marbled calf, smooth spine gilt, red label, cold fillet framing the boards, gilt roulette on the edges. (Small traces of damp-staining on the upper margin on about ten pages). First French translation, with Latin text opposite, by François-Alexandre Aubert de la Chesnaye des Bois of this work on sea urchins first published in 1734 under the Latin title "Naturalis Disposito Echinodermatum" by Jacob Theodor Klein. François-Alexandre Aubert de la Chesnaye des Bois (1699-1784) is a French writer, genealogist and compiler. La Chenaye des Bois is mainly known for his publications on the genealogy of noble families and especially his "Dictionnaire de la Noblesse". Jacob Theodor Klein (1685-1759) is a German marine zoologist, naturalist, lawyer, botanist and member of the Royal Society. He had one of the richest natural history cabinets in Europe. His collection of sea urchins, parts of which are kept in the State Zoological Collection in Munich, is considered a valuable source of scientific material for zoologists and paleontologists. Klein is known, among other things, for having built a classification system intended to rival that of Carl von Linné (1707-1778; Swedish naturalist) and for having founded the botanical garden of Ogród Botaniczny w Oliwie in Gdansk. He "had many and varied interests in natural history besides sea urchins. He developed a botanical garden in Danzig, founded and directed a society of naturalists there, made extensive collections, and published about two dozen monographs, including studies of birds, fishes, reptiles, and invertebrates other than sea urchins, especially mollusks" (D.S.B.) His seminal treatise on sea urchins, recognized as one of the major works on the subject until the 19th century, summarizes the author's feelings on taxonomic methods. His method is based entirely on external characteristics, such as the number and position of the limbs and mouth, and he vigorously opposes any method, including the Linnaean system, based on characters that are not externally visible. His work also contains a "general table of a zoological method" [translated from French] classifying animals that have feet and those that do not. The illustration consists of an attractive portrait of Klein standing in front of his natural history cabinet and 28 plates engraved by Maisonneuve representing various species of sea urchins. The last 6 plates are engraved after Humblot's original drawings of sea urchins that were in the cabinet of René-Antoine Ferchault de Réaumur (1683-1757; French physicist, mathematician, meteorologist, naturalist and director of the Académie des Sciences).

‎Frist printing of Klein's paper on the icosahedron.""A problem that greatly interested Klein was the solution of fifth-degree equations, for its treatment involved the simultaneous consideration of algebraic group theory, geometry, differential equations, and function theory. Hermite, Kronecker, and Brioschi had already employed transcendental methods in the solution of the general algebraic equation of the fifth degree. Klein succeeded in deriving the complete theory of this equation from a consideration of the icosahedron, one of the regular polyhedra known since antiquity. These bodies sometimes can be transformed into themselves through a finite group of rotations. The icosahedron in particular allows sixty such rotations into itself. If one circumscribes a sphere about a regular polyhedron and maps it onto a plane by stereographic projection, then to the group of rotations of the polyhedron into itself there corresponds a group of linear transformations of the plane into itself. Klein demonstrated that in this way all finite groups of linear transformations are obtained, if the so-called dihedral group is added. By a dihedron Klein meant a regular polygon with n sides, considered as rigid body of null volume."" (DSB VII, p. 400).The icosahedron is a regular polyhedron with 20 identical equilateral triangular faces, 30 edges and 12 vertices. It is one of the five Platonic solids.‎

‎First appearance of the important paper which constitutes one of the first results obtained from the study of quantum electrodynamics and ""played an important role in discussions of the applicable limits of quantum mechanics to studies of cosmic rays and nuclear physics."" (DSB).""In early 1928 Nishina returned to Copenhagen and worked with Oskar Klein. As a result of their cooperation, the Klein-Nishina formula was completed in October of the same year, before Nishina's return to Japan. In 1923 the quantum (particle) nature of X rays was discovered by Arthur Compton. Nishina had once made an experimental approach to this phenomena at the Cavendish Laboratory. The relation among the increased wavelength of the scattered X rays, the energy of recoiled electrons, and the scattering angle was accounted for by the quantum nature. In 1928 Nishina and Klein calculated the cross section and intensity of the Compton scattered radiation by the use of Dirac's new relativistic quantum mechanics of electrons. They succeeded in a complicated calculation by doing this separately and checking it together. (Nishina also brought this method of calculation with a team back to Japan.)Nishina and Klein searched for the solution of Dirac's wave equation in the case of a free electron (initially at rest) in the field of a plane electromagnetic wave."" (DSB).The Klein-Nishina was one of the first results obtained from the study of quantum electrodynamics. Consideration of relativistic and quantum mechanical effects allowed the development of an accurate equation for the scattering of radiation from a target electron. Before this derivation, the electron cross section had been classically derived by the British physicist and discoverer of the electron, J.J. Thomson. However, scattering experiments showed significant deviations from the results predicted by the Thomson cross section. Further scattering experiments agreed perfectly with the predictions of the Klein-Nishina formula.‎

‎<p>Avant de devenir Yves le Monochrome, Yves Klein, l’homme du bleu devenu aujourd’hui un mythe, se passionne pour le judo. C’est ce qui le pousse en 1952 à aller jusqu’au Japon, où il obtient sa ceinture noire 4e dan. Quelques mois après son retour en France, à la fin de l’année 1954, Yves Klein publiera d’ailleurs quasi simultanément Les Fondements du judo et Yves Peintures, considéré comme son premier geste d’artiste. Ce long séjour au Japon, nourri de rencontres et de découvertes, marque assurément Yves Klein qui y fait souvent allusion, et continue d’alimenter les interrogations de tous ceux qui s’intéressent à son oeuvre. Celle-ci y puiserait-elle sa source ?

‎First edition. In these groundbreaking papers Klein established that if Euclidean geometry is consistent then non-Euclidean geometry is consistent as well and he introduces the adjectives ""parabolic"", ""elliptic"", and ""hyperbolic"" for the respective geometries of Georg Riemann, of Nicolai Lobachevsky, of C.F. Gauss and Janos Bolyai. ""Cayley's idea (that metrical geometry is part of projective geometry) was taken over by Felix Klein (1849-1925) and generalized so as to include the non-Euclidan geometries. Klein, a professor at Göttingen, was one of the lading mathematicians in Germany during the last part of the nineeeeteenth and first part of the twentieth century. During the years 1869-70 he larned the work of Lobatchevsky, Bolyai, von Staudt, and Cayley"" however, even in 1871he did not know Laguerre's result. It seemed to him to be posible to subsume the non-Euclidean geometries, hyperbolic, and double elliptic geometry, under projective geometry byexploiting Cayley's idea. He gave a sketch og his thoughts in a paper of 1871, and then developed them in two papers (1871 a. 1873, the ppers offered here). Klein was the first to obtain models of non-Euclidean geometries.""

‎First printing of Poincaré's paper on his comprehensive theory of complex-valued functions which remain invariant under the infinite, discontinuous group of linear transformations. In 1881 Poincaré had published a few short papers with some initial work on the topic, and in the 1881, Klein invited Poincaré to write a longer exposition of his results to Mathematische Annalen which became the present paper. This, however, turned out to be an invitation to at mathematical dispute:""Before the article went to press, Klein forewarned Poincaré that he had appended a note to it in which he registered his objections to the terminology employed therein. In particular, Klein disputed Poincaré's decision to name the important class of functions possessing a natural boundary circle after Fuch's, a leading exponent of the Berlin school. The importance he attached to this matter, however, went far beyond the bounds of conventional priority dispute. True, Klein was concerned that his own work received sufficient acclaim, but the overriding issue hinged on whether the mathematical community would regard the burgeoning research in this field as an outgrowth of Weierstrassian analysis or the Riemannian tradition.""

‎First edition of these 2 papers which unifies the Euclidean and Non-Euclidean geometries, by reducing the differences to expressions of the ""distance function"", and introducing the concepts ""parabolic"", ""elliptic"" and ""hyperbolic"" for the geometries of Euclid, Riemann and of Lobatschewski, Gauss and Bolyai. He further eliminates Euclid's parallel-axiom from projective geometry, as he shows that the quality of being parallel, is not invariant under projections.Klein build his work on Cayley's ""distant measure"" saying, that ""Metrical properties are not properties of the figure per se but of the figure in relation to the absolute."" This is Cayley's idea of the general projective determination of metrics. The place of the metric concept in projective geometry and the greater generality of the latter were described by Cayley as ""Metrical geometry is part of projective geometry."" Cayley's idea was taken over by Felix Klein....It seemed to him to be possible to subsume the non-Euclidean geometries, hyperbolic and double elliptic geometry, under projective geometry by exploring Cayley's idea. He gave a sketch of his thoughts in a paper of 1871, and then developed them in two papers (the papers offered here).Klein was the first to recognize that we do not need surfaces to obtain models of non-Euclidean geometries....The import which gradually emerged from Klein's contributions was that projective geometry is really logically independent of Euclidean geometry....By making apparent the basic role of projective geometry Klein paved the way for an axiomatic development which could start with projective geometry and derive the several metric geometries from it.""(Morris Kline).The offred volumes cntains other importen mathematical papers by f.i. by Klebsch, Lipschitz, Neumann, Noether, Thomae, Gordan, Lie, Du Bois-Raymond, Cantor (Über trigonometrische Reihen),etc.(Sommerville: Bibliography of Non-Euclidean Geometry p. 45 a. 49.)‎

‎First printing of Klein's important contribution to non-Euclidean geometry. Klein saw a fundamental unity in the subject of non-Euclidean geometry. Rather than a heterogeneous collection of abstruse mathematics, non-Euclidean geometry was in Klein's view a ""concrete discipline"".For over two millennia geometry had been the study of theorems which could be proved from Euclid's axioms. However, in the beginning of the 19th century it was proved that there exist other geometries than that of Euclid. Motivated by the emergence of the new geometries of Bolyai, Lobachevsky, and Riemann, Klein proposed to define a geometry, not by a set of axioms, but instead in terms of the transformations that leave it invariant" according to Klein, a geometric structure consists of a space together with a particular group of transformations of the space. A valid theorem in that particular geometry is one that holds under this group of transformations. This controversial idea did not only give a more systematic way of classifying the different geometries, but also gave birth to new geometric structures such as manifolds.

‎Frist printing of Klein's paper on the icosahedron.""A problem that greatly interested Klein was the solution of fifth-degree equations, for its treatment involved the simultaneous consideration of algebraic group theory, geometry, differential equations, and function theory. Hermite, Kronecker, and Brioschi had already employed transcendental methods in the solution of the general algebraic equation of the fifth degree. Klein succeeded in deriving the complete theory of this equation from a consideration of the icosahedron, one of the regular polyhedra known since antiquity. These bodies sometimes can be transformed into themselves through a finite group of rotations. The icosahedron in particular allows sixty such rotations into itself. If one circumscribes a sphere about a regular polyhedron and maps it onto a plane by stereographic projection, then to the group of rotations of the polyhedron into itself there corresponds a group of linear transformations of the plane into itself. Klein demonstrated that in this way all finite groups of linear transformations are obtained, if the so-called dihedral group is added. By a dihedron Klein meant a regular polygon with n sides, considered as rigid body of null volume."" (DSB VII, p. 400).The icosahedron is a regular polyhedron with 20 identical equilateral triangular faces, 30 edges and 12 vertices. It is one of the five Platonic solids.The volume contain many other papers by contemporary mathematicians. ‎
