‎LA LITTERATURE DE LA REVOLUTION MONDIALE‎

‎Organe central de l’Union internationale des écrivains révolutionnaire, Edition d’Etat, Moscou, Leningrad, 1931. ‎

‎Une revue in-4°(18x25 cm), brochée, couverture souple éditeur, premier plat présenté dans le style des années 30, avec des lettres noires et rouges. Cette revue compte 158 pages , parmi lesquelles quelques illustrations en noir et des reproductions d’images du film d’Eisenstein (Cuirassé Potemkine). Au sommaire.... Pièces, Contes, Documentaires: Bruno JASIENSKI (Le Bal des Mannequins), N. TIKHONOV (Les Nomades), FOUDJIMORI-SEYKITI (L’Homme qui n’applaudissait pas). LUTCHÉ-TSINQ (A la Conférence des Soviets de Chine). Articles: A SELIVANOVSKI (La Littérature Prolétarienne de M. Poulaille), A. STOLIAROV (Le Freudisme et les “Freudo-marxistes”), PLEKHANOV (L’Art et la Vie Sociale), ANISSIMOV (Les films de S.Eisenstein). Chronique Internationale: URSS, Tchécoslovaquie, Hongrie, Lithuanie, Roumanie, Bulgarie, Pologne, Japon, Chine. Cette revue ne connut que 6 numéros dont le premier fit scandale (il marqua même le début de la séparation entre communistes et surréalistes). La cause en fut un poème d’ARAGON qui attira des ennuis judiciaires à ARAGON (lequel était le rédacteur en chef de l’édition française), un poème dont deux vers disaient “ Camarades/ Descendez les flics!”… En tout cas la puissance de notre exemplaire –le numéro 3 de la série- reste d’un haut niveau de combativité et d’analyse même s’il peut paraître inférieur à celui du N° 1.

‎Über die Irreductibilität und einige andere Eigenschaften der Gleichung, von welcher die Theilung der ganzen Lemniscate abhängt (+) Über eine allgemeine Eigenschaften der Gleichung, von welcher die Theilung der ganzen Lemniscate abhängt, nebst Anwendu... - [Eisenstein's Criterion]‎

‎Berlin, G. Reimer, 1850. 4to. Bound in later marbled wrappers, as extracted from ""Journal für die reine und angewandte Mathematik, 28 Band, 4. Heft, 1844"". Very fine and clean. Pp. 160-179" Pp. 224-274 Pp. 275-287 [Entire issue: 289-380 + 2 folded plates].‎

‎First publication of lemniscate function and Eisenstein's Criterion, one of the best known irreducibility criteria of polynomials. It is often seen referred to as the Schönemann-Eisenstein. Euler had introduced and studied the arc length of the lemniscate in the 18th century, this work laying the ground work for the later development of elliptic functions. The lemniscate function expresses the parameter of the lemnicate in terms of its arc-length. It can be extended to complex values of the parameter, and it then makes sense to ask for the points which divide the lemniscate into m equal parts, where m is a Gaussian integer (a complex number). Abel had shown that the determination of these points reduced to finding the roots of a certain polynomial equation. A crucial point in Eisenstein's extension of Abel's work described in the present papers was to prove that this polynomial is irreducible. Eisenstein developed his eponymous criterion to establish this (although today it is most familiar when applied to the more elementary case of a polynomial with ordinary integer coefficients).‎

‎First printing of German mathematics prodigy Eisenstein's paper on third degree equations with basis in a devided circle. Even though he died prematurely at the age of 29, he managed to prove biquadratic reciprocity, Quartic reciprocity, Cubic reciprocity, to be imprisoned by the Prussian army for revolutionary activities in Berlin and making Gauss state that: ""There have been only three epoch-making mathematicians: Archimedes, Newton, and Eisenstein"". Alexander von Humboldt, then 83, accompanied Eisenstein's remains to the cemetery. The papers presented in the present issue is among his most prominent and made him famous throughout the mathematical world. (James, Driven to innovate, P. 88). ""The twenty-seventh and twenty-eighth volumes of Crelle's Journal, published in 1844, contained twenty-five contributions by Eisenstein. These testimonials to his almost unbelievable, explosively dynamic productivity rocketed him to fame throughout the mathematical world. They dealt primarily with quadratic and cubic forms, the reciprocity theorem for cubic residues, fundamental theorems for quadratic and biquadratic residues, cyclotomy and forms of the third degree, plus some notes on elliptic and Abelian transcendentals. Gauss, to whom he had sent some of his writings, praised them very highly and looked forward with pleasure to an announced visit. In June 1844, carrying a glowing letter of recommendation from Humboldt, Eisenstein went off to see Gauss. He stayed in Göttingen fourteen days. In the course of the visit he won the high respect of the ""prince of mathematicians,"" whom he had revered all his life. The sojourn in Göttingen was important to Eisenstein for another reason: he became friends with Moritz A. Stern-the only lasting friendship he ever made. While the two were in continual correspondence on scientific matters, even Stern proved unable to dispel the melancholy that increasingly held Eisenstein in its grip. Even the sensational recognition that came to him while he was still only a third-semester student failed to brighten Eisenstein's spirits more than fleetingly. In February 1845, at the instance of Ernst E. Kummer, who was acting on a suggestion from Jacobi (possibly inspired by Humboldt), Eisenstein was awarded an honorary doctorate in philosophy by the School of Philosophy of the University of Breslau.Eisenstein soon became the subject of legend, and the early literature about him is full of errors. His treatises were written at a time when only Gauss, Cauchy, and Dirichlet had any conception of what a completely rigorous mathematical proof was. Even a man like Jacobi often admitted that his own work sometimes lacked the necessary rigor and self-evidence of methods and proofs."" (DSB)‎
