Abstract:

We construct approximate transport maps for non-critical $\beta$-matrix models, that is, maps so that the push forward of a non-critical $\beta$-matrix model with a given potential is a non-critical $\beta$-matrix model with another potential, up to a small error in the total variation distance. One of the main features of our construction is that these maps enjoy regularity estimates which are uniform in the dimension. In addition, we find a very useful asymptotic expansion for such maps which allow us to deduce that local statistics have the same asymptotic behavior for both models.
