Miriam Cohen (born October 1941) is an Israeli mathematician and a professor in the Department of Mathematics at Ben-Gurion University of the Negev whose main areas of research are Hopf algebras, quantum groups and non-communicative rings.
His use of the Yang-Baxter equation led to the formulation and the study of representations of the quantum group by Vladimir Drinfeld in the 1980s, and quantum generalizations of affine algebras, and they are quasi-triangular Hopf algebras which yield solutions of the Yang-Baxter equation and provide insight into the properties of corresponding statistical models.
Drinfeld introduced the notion of a quantum group (independently discovered by Michio Jimbo at the same time) and made important contributions to mathematical physics, including the ADHM construction of instantons, algebraic formalism of the Quantum inverse scattering method, and the Drinfeld–Sokolov reduction in the theory of solitons.
