It is a long-lasting combination of inattention, … 5 Jan 2026 11:15 to 12:15 Event Alice Guionnet About Non-Commutative Entropy and Topology Symposium Abstract In the 1990s, Voiculescu developed the theory of non-commutative entropy. 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.

Hurtado we showed that for … 28 Jan 2026 14:00 to 14:50 Event Michael Magee Geometry and spectrum of large objects (2) Symposium 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 … 28 Jan 2026 15:00 to 15:50 Event Maria Melchior Mental health and addictions: from the intimate to the population-based Opening lecture Documents and media Download support Download the press release Read the interview "Young people's mental health has been deteriorating for several years" Abstract Mental health and addiction are broad concepts, covering heterogeneous symptoms and … 4 Dec 2025 18:00 to 19:00 Event Thierry Escaich Composing today Special events Masterclass with Thierry Escaich , organist and composer.
