Title: Control of eigenfunctions on negatively curved manifoldsAbstract: Semiclassical measures are a standard object studied in quantum chaos, capturing macroscopic behavior of sequences of eigenfunctions in the high energy limit. They have a long history of study going back to the Quantum Ergodicity theorem and the Quantum Unique Ergodicity conjecture. I will speak about the […]

Title: 2-categorical affine symmetries and quantum boson algebrasAbstract: Representations of KLR (quiver Hecke) algebras categorify the positive part of the quantum group associated to any symmetrizable Cartan matrix. This categorical perspective makes certain symmetries more natural to study. For example, the induction and restriction functors between categories of KLR algebra modules play an important role […]

Title: On rational multisections of conic bundlesAbstract: The Enriques criterion for unirationality of conic bundles states that if X is a conic bundle over P^2, then X is unirational if and only if the conic bundle admits a rational multisection. Furthermore, if X is unirational but not rational, then such a rational multisection necessarily has even degree. […]
