Hjalmar Rosengren

Professor at Analysis and Probability Theory

The research area of Hjalmar Rosengren is special functions, with an emphasis on relations to other areas such as representation theory, combinatorics, number theory and mathematical physics. During recent years the main focus has been on the eight-vertex model and other elliptic lattice models of statistical mechanics, and their relation to elliptic quantum groups, elliptic hypergeometric functions and algebraic solutions of Painlevé equations.
