‎Mémoire sur les Fonctions fuchsiennes.‎

‎[Berlin, Stockholm, Paris, F. & G. Beijer, 1882]. Large4to. As extracted from ""Acta Mathematica"", In ""Acta Mathematica"", volume 1. Clean and fine. Pp. 193-294.‎

‎First printing of Poincaré's famous paper which conjectured the uniformization theorem for (the Riemann surfaces of) algebraic curves. It also constitute the second paper in Poincaré's exceedingly important series of six paper's which together represent the discovery of Automorphic Functions. ""Before he was thirty years of age, Poincaré became world famous with his epoch-making discovery of the ""automorphic functions"" of one complex variable (or, as he called them, the ""fuchsian"" and ""kleinean"" functions)."" (DSB).These manuscripts, written between 28 June and 20 December 1880, show in detail how Poincaré exploited a series of insights to arrive at his first major contribution to mathematics: the discovery of the automorphic functions. In particular, the manuscripts corroborate Poincaré's introspective account of this discovery (1908), in which the real key to his discovery is given to be the recognition that the transformations he had used to define Fuchsian functions are identical with those of non-Euclidean geometry.The idea was to come in an indirect way from the work of his doctoral thesis on differential equations. His results applied only to restricted classes of functions and Poincaré wanted to generalize these results but, as a route towards this, he looked for a class functions where solutions did not exist. This led him to functions he named Fuchsian functions after Lazarus Fuchs but were later named automorphic functions. First editions and first publications of these epochmaking papers representing the discovery of ""automorphic functions"", or as Poincaré himself called them, the ""Fuchsian"" and ""Kleinian"" functions.""By 1884 Poincaré published five major papers on automorphic functions in the first five volumes of the new Acta Mathematica. When the first of these was published in the first volume of the new Acta Mathematica, Kronecker warned the editor, Mittag-Leffler, that this immature and obscure article would kill the journal. Guided by the theory of elliptic functions, Poincarë invented a new class of automorphic functions. This class was obtained by considering the inverse function of the ratio of two linear independent solutions of an equation. Thus this entire class of linear diffrential equations is solved by the use of these new transcendental functions of Poincaré."" (Morris Kline).Poincaré explains how he discovered the Automorphic Functions: ""For fifteen days I strove to prove that there could not be any functions like those I have since called Fuchsian functions, I was then very ignorant" every day I seated myself at my work table, stayed an hour or two, tried a great number of combinations and reached no results. One evening, contrary to my custom, I drank black coffee and could not sleep. Ideas rose in crowds I felt them collide until pairs interlocked, so to speak, making a stable combination. By the next morning I had established the existence of a Class of Fuchsian functions, those which come from hypergeometric series" i had only to write out the results, which took but a few hours...the transformations that I had used to define the Fuchsian functions were identical with those of Non-Euclidean geometry...""‎

‎Paris, Gauthier-Villars, 1905. 4to. No wrappers. In: ""Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences"", Tome 140, No 23. Titlepage to vol. 140. Pp. (1497-) 1572. (Entire issue offered). Poincaré's paper: pp. 1504-1508. Titlepage with a stamp on verso. A bit of upper right corner gone. Leaves a bit fragile, caused by the poor paperquality. Clean.‎

‎First printing of this famous paper delivered to the Academy of Paris on its session of June 1905, as the first Poincaré relativistic text ""On the dynamic of electron"", where Poincaré set forth the essential element of relativity and the ""Lorentz Transformation"". Poincaré concludes ""It seems that this impossibility of demonstrating absolute motion is a general law of nature"" !! and that Newton's law need modification and that there should exist gravitational waves which propagate with the velocity of light !! - This famous paper gave rice to the controversy about priority around the discovery of special relativity as Poincaré's paper is from June 5 and Einstein's first paper on relativity was received by the ""Annalen"" on June 30, both 1905.""The official history tells us that Einstein, without having read the works of Lorentz and Poincaré past 1895 and without any prior publication on the subject, had written alone in Bern the ""founder paper"" of the Relativity in the last days of June 1905. For that reason, and a few other of less importance, the biographers of Einstein have called that year 1905 ""Annus mirabilis"" and its centenial is celebrated in 2005. However on June 5, 1905, after many other papers on this subject, Poincaré had presenteda note at the French Academy of Science, a text that contains the essential elements of Einstein paper: the relativity principle and the ""Lorentz transformation"". This coincidence involves the suspicion of a possible plagiarism of Poincaré by Einstein."" (C. Marchal ""Poincaré, Einstein and the Relativity: the Surprising Secret.""‎

‎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.""

‎Tome II des mémoires de l'auteur (“Au Service de la France. Neuf années de Souvenirs”). — "Un volume plein de vie et de dramatique intérêt qui nous fait revivre l'année 1912, durant la première guerre balkanique, c'est-à-dire aux origines de la grande guerre. Dès le printemps de 1912, on voit poindre la guerre balkanique. M. Poincaré, le premier, aperçoit le péril, s'en alarme, travaille à le prévenir. M. Sazonof se croit assuré de pouvoir, à son gré, retenir les États balkaniques qui lui ont promis de ne rien précipiter sans son agrément; c'est M. Poincaré qui, durant sa visite à Pélersbourg, lui montre, dans l'alliance serbo-bulgare, la pointe offensive. L'intrigue autrichienne, dans les Balkans, s'entrecroise avec l'intrigue russe ; M. Poincaré voit nettement que la résolution des petits États, poussés à bout par la maladresse des Jeunes-Turcs à l'égard des chrétiens de Macédoine, peut, à un moment donné, déclencher la guerre, en dépit des recommandations des Puissances. Comment la victoire des Bulgares, et surtout celle des Serbes et des Grecs, fut une surprise pour tous les gouvernements et apparut à quelques-uns comme une catastrophe, des documents précis nous le montrent. La crise de 1912, conséquence de celle de 1909, est comme la répétition générale de celle de 1914 où, délibérément, l'Allemagne et l'Autriche voulurent ou l'humiliation de la Russie et son abdication dans les Balkans, ou la guerre. Ces conséquences, M. Poincaré les prévoit dès 1912. Il se montre, à la lumière des documents, le défenseur résolu des intérêts de la France, fidèle à ses engagements sans les dépasser jamais, et le meilleur ouvrier de la paix européenne." (René Pinon, Revue des Deux Mondes, 1926) — "M. Raymond Poincaré rassemble et publie les souvenirs de sa vie politique de 1911 à 1920 en une série de volumes dont chacun porte un titre spécial. Le récit suit strictement l'ordre chronologique, il contient de nombreuses pièces inédites (memoranda, dépêches, lettres privées, etc.). Ce deuxième volume est un témoignage de tout premier ordre, en particulier sur les affaires d'Orient de 1912-1913 et les relations avec la Russie pendant la guerre balkanique." (Raymond Guyot, Revue Historique) — "Grâce aux copies de documents qu'il avait en sa possession, M. Poincaré a été à même de livrer à la publicité quantité de pièces inédites de grande valeur. Il va de soi que ces souvenirs ont provoqué de vives polémiques. Mais personne, je crois, n'a contesté la largeur de vues, la fermeté de pensée, la vigueur de certaines démonstrations, qui font de ces volumes de fortes pages d'histoire."

‎Notice sur la distribution et marche des pluies dans la département de la Meuse, le bassin supérieur de la rivière Meuse et une zone avoisinante du bassin de la Seine‎

‎Paris, Dunod, 1873, in-8, 43, (1) pages et (2) cartes depl, broché, couverture imprimée de l'éditeur, Rare tiré à part non coupé. A travers cette brochure, Poincaré traite des trois modes de représentation (isoombres, suivies et horaires) des phénomènes météorologiques, modes employés avec beaucoup de réticence à l'époque. Il explique notamment les légendes des deux cartes qu'il a réalisées pour représenter les pluies tombées sur la Meuse et le bassin de la Seine durant l'hiver 1868-1869. En 1871, Poincaré présente à la Commission de l'Association Scientifique de France une étude en 7 parties intitulée "études sur la distribution et la marche des pluies dans la région". Un résumé sera publié peu après dans le n° 211 de la revue hebdomadaire de l'institution. Antoine Poincaré, polytechnicien et ingénieur en chef à Bar-le-Duc fut l'oncle du mathématicien et physicien Henri Poincaré et le père de Raymond Poincaré, président de la France de 1913 à 1920. Malgré la présence minime de rousseurs et de taches sur les couvertures, bel exemplaire. Couverture rigide‎

‎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 printing of these important papers: POINCARÉ: First edition. ""As soon as he came into contact with the work of Riemann and Weierstrass on Abelian Functions and algebraic geometry, Poincaré was very much attracted by those fields. His papers on these subjects occupy in his complete works as much space as those on automorphic functions, their dates ranging from 1881 to 1911. One of his main ideas in these papers is that of ""reduction"" of Abelian functions. Generalizing particular cases studied b Jacobi, Weierstrass, and Picard, Poincaré proved the general ""complete reducibility"" theorem...""(DSB).VOLTERRA: First edition. As the north and south poles, instead of being fixed points on the earth's surface, wander round within a circle of ab. 5o ft. in diameter, the result is a variability of terrestial latitudes generally. Volterra gives an elaborate mathematical analysis of these yearly fluxtuations.‎

‎First appearance in print of the discovery of the automorphic forms, which Poincaré named Fuchsian functions.""One of Poincaré's first discoveries in mathematics, dating to the 1880s, was automorphic forms. He named them Fuchsian functions, after the mathematician Lazarus Fuchs, because Fuchs was known for being a good teacher and had researched on differential equations and the theory of functions. Poincaré actually developed the concept of these functions as part of his doctoral thesis. Under Poincaré's definition, an automorphic function is one which is analytic in its domain and is invariant under a discrete infinite group of linear fractional transformations. Automorphic functions then generalize both trigonometric and elliptic functions."" (Wikipedia).‎
