For a single non-commutative variable, this entropy reduces to the rate function of the empirical measure of the eigenvalues of a Gaussian matrix. For several … 28 Jan 2026 10:00 to 10:50 Event Jean Raimbault A Priori Bounds for the Homology of Arithmetic Manifolds Symposium 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.
