Abstract:
Topological expansion is a method of representing a random matrix computation as a sum over topological gluings. This method is particularly useful in the multi-matrix setting in which we consider expressions in independent and in-general-position matrices. We will discuss topological expansion for β-matrices, where β is the Dyson parameter interpolating between the real case β=1, the complex case β=2, and the quaternionic case β=4.
