La correspondance entre Henri Poincar, les astronomes, et les godsiens [Hardcover]

The lettersin this volume cover Poincar?'s multifaceted career in astronomy in itsentirety, extending from the time of his first publications in 1880 to the endof his life in 1912. At a tender age, Poincar? established his authority inquestions of celestial mechanics, and his views were soon sought after on avast array of questions by the leading astronomers and geodesists of his time,including C.V.L. Charlier, G.H. Darwin, H. Faye, F.R. Helmert, G. W. Hill, A.Lindstedt, A.M. Liapunov, N. Lockyer, S. Newcomb, K. Schwarzschild, and F.Tisserand. Poincar? and his correspondents take up topics ranging from thethree-body problem and perturbation theory to the determination of the geoideand the equilibrium figures of rotating fluid masses. The volume also shedslight on Poincar?'s three terms as president of the Bureau of Longitudes, wherehe guided French astronomy and geodesy through ambitious projects, such as themeasurement of an arc of meridian near Quito.

Les lettres du troisi?me volume de la Correspondance de Poincar? scandent toute son Suvre astronomique, allant de ses premiers m?moires sur les courbes d?finies par une ?quation diff?rentielle (1881), jusqu'aux analyses des hypoth?ses cosmogoniques (1911). Encore tr?s jeune, Poincar? s'est fait remarquer pour sa ma?trise des questions de la m?canique c?leste, de tel sorte que les astronomes et les g?od?siens l'ont souvent interpell?, y compris O. Callandreau, C.V.L. Charlier, G.H. Darwin, F.R. Helmert, A. Lindstedt, A.M. Lyapunov, Simon Newcomb, Karl Schwarzschild et F. Tisserand.

Avec ses correspondants, Poincar? abordaient les questions principales de l'astronomie math?matique, du c?l?bre probl?me des trois corps ? la th?orie des perturbations et aux figures d'?quilibre des masses fluides en rotation. La correspondance de Poincar? ?dit?e et annot?e dans ce volume concerne, au-del? des m?moires math?mló,
