‎---- EDITION ORIGINALE du cours donné par G. Darboux à la Sorbonne ---- BEL EXEMPLAIRE ---- TOUS LES VOLUMES SONT EN EDITIONS ORIGINALES ---- "In 1878, Darboux became suppléant of Chasles at the Sorbonne and two years later succeeded Chasles in the chair of higher geometry which he held until his death... He was primarily a geometer but had the ability to use both analytic and synthetic methods, notably in the theory of differential equations... Darboux's approach to geometry is fully displayed in his four-volume Leçons sur la théorie générale des surfaces based on his lectures at the Sorbonne. This collection of elegant essays on the application of analysis to curves and surfaces is held together by the author's deep understanding of the connections of various branches of mathematics. There are many applications and excursions into differential equations and dynamics. Among the subjects covered are that applicability and deformation of surfaces, the differential equation of Laplace and its applications and the study of geodesics and of minimal surfaces. Typical is the use of the moving trihedral... ". (DSB III pp. 559/560) - Cajori p. 315 **5950/N3/N7AR-1515/M7AR-1518/CAV.E5-1506/CAV.E5‎
