Shlomo Sternberg (2019) A Mathematical Companion to Quantum Mechanics Dover Publications ISBN 9780486826899 ISBN 0486826899.Sternberg is described by rabbi Herschel Schachter of Yeshiva University as "a big genius in learning and math" who played a role in establishing that swordfish is kosher. He was among the mathematicians who debunked the mathematics foundations of Michael Drosnin's controversial claims in The Bible Code. He has worked with Yuval Ne'eman on supersymmetry in elementary particle physics, exploring from this perspective the Higgs mechanism, the method of spontaneous symmetry breaking and a unified approach to the theory of quarks and leptons. Sternberg has, in addition, played a role in recent developments in theoretical physics. He also published the more recent " Curvature in mathematics and physics". His "Lectures on Differential Geometry" is a popular standard textbook for upper-level undergraduate courses on differential manifolds, the calculus of variations, Lie theory and the geometry of G-structures. Sternberg's contributions to symplectic geometry and Lie theory have also included a number of basic textbooks on these subjects, among them the three graduate level texts with Victor Guillemin: "Geometric Asymptotics," "Symplectic Techniques in Physics", and "Semi-Classical Analysis". This theorem, the "AGS convexity theorem," was simultaneously proved by Guillemin-Sternberg and Michael Atiyah in the early 1980s. This last work was also the inspiration for a result in equivariant symplectic geometry that disclosed for the first time a surprising and unexpected connection between the theory of Hamiltonian torus actions on compact symplectic manifolds and the theory of convex polytopes. Together with Victor Guillemin he gave the first rigorous formulation and proof of a hitherto vague assertion about Lie group actions on symplectic manifolds, namely the Quantization commutes with reduction conjecture. Together with David Kazhdan and Bertram Kostant, he showed how one can simplify the analysis of dynamical systems of Calogero type by describing them as symplectic reductions of much simpler systems. For instance, together with Bertram Kostant he showed how to use reduction techniques to give a rigorous mathematical treatment of what is known in the physics literature as the BRS quantization procedure. Sternberg provided major contributions also to the topic of Lie group actions on symplectic manifolds, in particular involving various aspects of the theory of symplectic reduction. As a by-product, they also obtained the " integrability of characteristics" theorem for over-determined systems of partial differential equations. Also, together with Victor Guillemin and Daniel Quillen, he extended this classification to a larger class of pseudogroups: the primitive infinite pseudogroups. In the 1960s Sternberg became involved with Isadore Singer in the project of revisiting Élie Cartan's papers from the early 1900s on the classification of the simple transitive infinite Lie pseudogroups, and of relating Cartan's results to recent results in the theory of G-structures and supplying rigorous (by present-day standards) proofs of his main theorems. He also proved generalizations of the Birkhoff canonical form theorems for volume preserving mappings in n-dimensions and symplectic mappings, all in the smooth case. Sternberg's first well-known published result, based on his PhD thesis, is known as the "Sternberg linearization theorem" which asserts that a smooth map near a hyperbolic fixed point can be made linear by a smooth change of coordinates provided that certain non-resonance conditions are satisfied. Sternberg was elected member of the American Academy of Arts and Sciences in 1969, of the National Academy of Sciences in 1986, of the Spanish Royal Academy of Sciences In 1999, and of the American Philosophical Society in 2010. He delivered the AMS Colloquium Lecture in 1990 and the Hebrew University's Albert Einstein Memorial Lecture in 2006. Īmong other honors, Sternberg was awarded a Guggenheim fellowship in 1974 and a honorary doctorate by the University of Mannheim in 1991. Since 2017, he is Emeritus Professor at the Harvard Mathematics Department. Īfter postdoctoral work at New York University (1956–1957) and an instructorship at University of Chicago (1957–1959), Sternberg joined the Mathematics Department at Harvard University in 1959, where he was George Putnam Professor of Pure and Applied Mathematics until 2017. Sternberg earned his PhD in 1955 from Johns Hopkins University, with a thesis entitled " Some Problems in Discrete Nonlinear Transformations in One and Two Dimensions", supervised by Aurel Wintner. Shlomo Zvi Sternberg (born 1936), is an American mathematician known for his work in geometry, particularly symplectic geometry and Lie theory.
