‎Edmund Landau - L.A.S. Mathématiques FIBONACCI Calculs Laisant & Painlevé - 1899‎

‎Longue lettre autographe signée, Mathématiques FIBONACCI Laisant Painlevé, 1899 Mathématicien allemand Exceptionnelle et très longue lettre autographe signée d'Edmund LANDAU, adressée au mathématicien français Charles-Ange LAISANT, datée du 31 Octobre 1899 à Paris. Rédigée à l'encre noire sur deux doubles feuillets de papier vélin, avec ses initiales gaufré bleues en entête. Cette lettre ne constitue pas une simple correspondance de courtoisie, mais un remarquable manuscrit mathématique préparatoire, qui documente la phase de recherche ayant conduit à la publication de 1899. En 1899, Charles-Ange Laisant pose le problème de la détermination de la somme des inverses des nombres de la suite de Fibonacci. Edmund Landau, alors jeune docteur de 22 ans à l'aube d'une carrière qui fera de lui l'un des plus grands théoriciens des nombres du siècle, s'empare de la question. Dans cette lettre, Landau répond directement à Laisant ( "Quant au problème que vous m'avez proposé hier soir, j'y ai réfléchi et suis parvenu aux résultats suivants..." ) et lui livre l'intégralité des calculs qui jetteront les bases directes de son article devenu une référence classique dans l'étude de cette série : "Sur la série des inverses des nombres de Fibonacci" , publié la même année dans le Bulletin de la Société Mathématique de France (Tome 27, p. 298-300). En introduction, Landau évoque ses démarches pour entrer à la Société Mathématique de France (SMF), révélant un double parrainage d'une immense distinction : Paul Painlevé et Charles-Ange Laisant lui-même. "Je viens d'avoir parlé à M. Painlevé. Il veut bien avoir l'obligeance de me présenter à la société mathématique de France ; mais, étant empêché d'assister à la séance suivante, il vous prie de dire en son nom qu'il me servira de parrain ensemble avec vous." Landau déploie une démonstration magistrale pour ramener la somme des inverses aux indices impairs de la suite de Fibonacci à des fonctions connues. Il utilise et cite explicitement : - La formule de Binet pour les termes de Fibonacci (un). - La transformation de la série en produits et sommes infinies complexes. - Les fonctions Thêta (ϑ) de Heinrich Weber ("les fonctions désignées par ϑ00(0) et ϑ10(0) dans le traité de M. Weber") . - La célèbre formule de produit infini de Gauss ("en faisant usage de la formule de Gauss..."). Landau conclut avec une remarquable lucidité sur les limites de l'analyse de son époque concernant les indices pairs : "l'étude de la somme des nombres inverses [pairs] semble dépasser les moyens actuels de l'analyse, tandis que celle des nombres 1/u11/u3... a été ramenée à des fonctions connues."

‎First editions of these fundamental papers in the development of quantum field theory. The process of measuring electromagnetic fields involves the observation of charged test bodies in those fields. Therefore the theory of electrodynamics is an inseparable extension of mechanics. A quantum theory of fields thus inherits, in some form, the limitations of measurement which lie at the foundation of quantum mechanics. In 1931 Landau and Peierls published a critical analysis of the consequences of such limitations in a relativistic quantum theory of fields (second paper offered). Landau and Peierls came to the negative conclusion that in several cases, the concept of momentum was without physical meaning and quantities such as the strength of a field was un-measurable. In their famous paper from 1933 Bohr and Rosenfeld (first paper offered) carefully reviewed the arguments of Landau and Peierls and showed, through the use of particular measuring arrangements, that a consistent quantum theory of fields is possible without further limitations than the ones which secure the consistency of quantum mechanics. The BR-paper is often credited with having laid the foundation for quantum electrodynamics. Bohr continued his work in this field, and in 1937 he completed a manuscript entitled ""Field and Charge Measurement in Quantum Theory"", but this was never published. When, in the late 1940s the important work on QED by Tomonaga, Schwinger, Dyson, and Feynman appeared in The Physical Review, Bohr and Rosenfeld again joined and published the essentials of the 1937 manuscript in the same journal (third paper offered).See Abraham Pais: Bohr's Times, pp.358-364.

‎Horoldamba le petit Mongol ‎

‎Paris Calmann-Lévy 1957 Première édition. Un bel exemplaire de ce livre de photos français. Il s'agit à la fois de l'histoire d'un enfant mongol et d'un documentaire sur la vie en Mongolie, illustré tout au long par les belles photographies d'Ergy. Les photos sont en noir et blanc. Couvertures souples avec des détails et des photographies en rouge et noir sur les couvertures avant et arrière. Les couvertures présentent de légères bosses et un léger assombrissement. L'intérieur est impeccable. Ergy Landau (1896-1967) était une photographe franco-hongroise surtout connue pour ses portraits, ses nus féminins, ses travaux publicitaires et ses images dynamiques du Paris de l'entre-deux-guerres. Malgré ses contributions significatives à la photographie du XXe siècle, son nom reste moins reconnu que celui de nombre de ses contemporains masculins tels que Brassaï ou Robert Capa. Non paginé mais 46 pages. 31 cm x 22,5 cm.‎

‎First Edition. A lovely copy of this French photo book. Partly the story of a Mongolian child, partly a documentary of Mongolian life, it is illustrated throughout by Ergy's fine photographs. Black and white throughout. Soft covers with red and black detail and photographs to front and rear cover. There is fractional bumping and fractional darkening to the covers. Internally spotless throughout. Ergy Landau (18961967) was a Hungarian-French photographer best known for her portraits, female nudes, advertising work, and dynamic images of inter war Paris. Despite significant contributions to 20th-century photography, her name remains less recognised than many of her male contemporaries such as Brassaï or Robert Capa. Unpaginated but 46 pages. 31cm x 22.5cm.‎
