Drinfield defined a class of quantum groups named for this scientist whose finite-dimensional representations give rational  solutions to a quantum equation named for this man and Baxter.
Drinfield defined a class of quantum groups named for this scientist whose finite-dimensional representations give rational  solutions to a quantum equation named for this man and Baxter. A collaborator and this scientist, who is second  alphabetically, proved that the zeros of the partition function of ferromagnetic Ising models always lie on the unit circle.  This scientist and the same collaborator also suggested that weak interactions might allow a particle to decay into two or  three pions, thus resolving the tau-theta puzzle in a manner verified by Lederman and Madame Wu. With a different  collaborator, this scientist names (*) nonabelian gauge theories; a Clay Institute Millenium Prize Problem asks for an existence  proof for one such theory and its associated mass gap. For 10 points, name this scientist who hypothesized parity violation with  Lee and worked on a class of field theories with Mills.
