Seminar on affine Grassmannians

This semester we will run a seminar on affine Grassmannians. It will be devoted to the study of affine Grassmannians and their appearances in various branches of mathematics, which will be chosen according to the interests of the participants. The webpage of the seminar can be found here It will be frequently updated. The seminar will meet at 1 pm on Thursdays via Zoom, Meeting ID: 928 0506 1304.

Andrea Mondino - Optimal Transport, weak Laplacian bounds and minimal boundaries in non-smooth spaces with Lower Ricci Curvature bounds

The goal of the seminar is to report on recent joint work with Daniele Semola, motivated by a question of Gromov to establish a “synthetic regularity theory" for minimal surfaces in non-smooth ambient spaces.

In the setting of non-smooth spaces with lower Ricci Curvature bounds:
