Abstract In the past few years the notion of “strong convergence” of multi-matrix models has found applications across pure mathematics including to random graphs, operator algebras (in several ways), spectral theory of hyperbolic manifolds, and the …

Abstract It is well-known that the Betti numbers of nonpositively-curved manifolds are (under normalization of curvature and some additional assumptions) linearly bounded by their volume. In a joint work with M. Frączyk and S. Hurtado we showed that for …

Abstract The spectral gap (or bass note) of a closed hyperbolic surface is the smallest non-zero eigenvalue of its Laplacian. This invariant plays an important role in many parts of hyperbolic geometry. The talk will start with a brief introduction to the …
