Research

Research topics

My work is related, more or less directly, to the probabilistic study of gauge theories, on a two-dimensional Euclidean space-time or on graphs. I have studied the Yang-Mills measure on surfaces, its semi-classical limit, its “large N” limit. In the last few years, I have been interested in the geometry and statistical physics of graphs with a vector bundle and a connection.

In my work, I use parts of the differential geometry of principal bundles, the representation theory of classical compact Lie groups and symmetric groups, the theory of large random matrices, non-commutative probability, in particular free probability, the theory of determinantal point processes. I have occasionally used potential theory in the complex plane and large deviations.

Among the things I have not yet worked with, I am particularly interested in Chern–Simons theory and the Wess–Zumino–Witten model, quantum deformations of the Yang–Mills measure, the theory of regularity structures.
