Leonard Gross
Leonard Gross (born February 24, 1931) is an American mathematician and Professor Emeritus of Mathematics at Cornell University.
Gross has made fundamental contributions to mathematics and the mathematically rigorous study of quantum field theory.
Leonard Gross graduated from James Madison High School in December 1948. He was awarded an Emil Schweinberg scholarship that enabled him to attend college. He studied at City College of New York for one term and then studied electrical engineering at Cooper Union for two years. He then transferred to the University of Chicago, where he obtained a master's degree in physics and mathematics (1954) and a Ph.D. in mathematics (1958).
Gross taught at Yale University and was awarded a National Science Foundation Fellowship in 1959. He joined the faculty of the mathematics department of Cornell University in 1960. Gross was a member of the Institute for Advanced Study in 1959 and in 1983 and has held other visiting positions. He has supervised 35 doctoral students.
Gross serves on the editorial boards of the Journal of Functional Analysis, and Potential Analysis.
Gross's scientific work has centered on the mathematically rigorous study of quantum field theories and related mathematical theories such as statistical mechanics. His early works developed the foundations of integration on infinite-dimensional spaces and analytic tools needed for quantum fields corresponding to classical fields described by linear equations. His later works have been devoted to Yang–Mills theory and related mathematical theories such as analysis on loop groups.
Gross's earliest mathematical works were on integration and harmonic analysis on infinite-dimensional spaces. These ideas, and especially the need for a structure within which potential theory in infinite dimensions could be studied, culminated in Gross's construction of abstract Wiener spaces in 1965. This structure has since become a standard framework for infinite-dimensional integration.
Gross was one of the initiators of the study of logarithmic Sobolev inequalities, which he discovered in 1967 for his work in constructive quantum field theory and published later in two foundational papers in which he established these inequalities for the Bosonic and Fermionic cases. The inequalities were named by Gross, who established the inequalities in dimension-independent form, a key feature needed especially in the context of applications to infinite-dimensional settings such as for quantum field theories. Gross's logarithmic Sobolev inequalities proved to be of great significance well beyond their original intended scope of application, for example in the proof of the Poincaré conjecture by Grigori Perelman.
