Paris, Gauthier-Villars (for the Académie des Sciences de Paris), 1925. 8vo (25.2 x 16.5 cm). Half title (to the series), title page; 57 pp. Original printed wrappers. = Élie Joseph Cartan (1869-1951) "did fundamental work in the theory of Lie groups, differential systems (coordinate-free geometric formulation of PDEs), and differential geometry. He also made significant contributions to general relativity and indirectly to quantum mechanics. He is widely regarded as one of the greatest mathematicians of the twentieth century . Cartan showed how to use his concept of connection to obtain a much more elegant and simple presentation of Riemannian geometry. His chief contribution to the latter, however, was the discovery and study of the symmetric Riemann spaces, one of the few instances in which the initiator of a mathematical theory was also the one who brought it to its completion" (Wikipedia). Offprint (Fascicule IX) from Mémorial des Sciences Mathématiques. Handwritten dedication written and signed by Cartan to "mon collègue" . Moulins. Uncut.

In "Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences", Tome 174. 1815,(1) pp. (Entire volume offered). Cartan's papers: pp.437-439, 593-595, 734-737, 857-60, 1104-1107. First edition of these papers, in which Cartan intruced the concept of "Torsion", the main inspiration for Einstein in his searce for a unified field theory. The ECT of gravity is a modification of the General relativity Theory"The Einstein-Cartan theory, also known as the Einstein-Cartan-Sciama-Kibble theory, is a classical theory of gravitation similar to general relativity but relaxing the assumption that the affine connection has vanishing antisymmetric part (torsion tensor), so that the torsion can be coupled to the intrinsic angular momentum (spin) of matter, much in the same way in which the curvature is coupled to the energy and momentum of matter. In fact, the spin of matter in curved spacetime requires that torsion is not constrained to be zero but is a variable in the principle of stationary action. Regarding the metric and torsion tensors as independent variables gives the correct generalization of the conservation law for the total (orbital plus intrinsic) angular momentum to the presence of the gravitational field. The theory was first proposed by Élie Cartan in 1922 and expounded in the following few years. Dennis Sciama and Tom Kibble independently revisited the theory in the 1960s, and an important review was published in 1976. Albert Einstein became affiliated with the theory in 1928 during his unsuccessful attempt to match torsion to the electromagnetic field tensor as part of a unified field theory. This line of thought led him to the related but different theory of teleparallelism." (Wikipedia).…
