I shall survey certain results and open problems on nonlinear spectral gaps and super-expanders. Time permitting, I will also discuss recent partial progress (from joint work with P. Ivanisvili) on a closely related question in Discrete Harmonic Analysis.

This talk is part of the Geometric Group Theory (GGT) Seminar series.
