Research Interests
Apart from my graduate years spent on S-matrix theory, my interests have focused on quantum field theory in one form or another, with a weakness for exact solutions and low dimensions.
In the earlier period, I applied it to particle physics, to find the quark-gluon coupling constant using finite-energy sum rules, and in collaboration with Witten, exact S-matrices for certain field theories. I worked extensively on the Gross-Neveu model, discovering there the only known example of self-triality, exemplified by a theory which has three equivalent, mutually dual, representation, all with the same Lagrangian.
The transformation I discovered there was used byWitten to establish, in a transparent way, world-sheet supersymmetry in string theory. It has appeared more recen
