Title: Bounds for spectral projectors on the three-dimensional torusAbstract: Periodic functions can be expanded in Fourier series, a linear combination of exponentials indexed by the integers. Despite the explicitness of the involved expressions, it is a difficult problem to take information about the frequency support of a function and deduce information on the physical side. […]
Topology Seminar: Fan Zhou (Columbia University)
Title: Categorifying Jacobi-TrudiAbstract: We discuss a way to categorify the famous Jacobi-Trudi identity by constructing a quasi-hereditary algebra A with a map kS_n to A; the “dominant simple” of A admits a BGG resolution, and after restricting to kS_n, we obtain a resolution of a simple module of kS_n by permutation modules. The algebra A […]
Number Theory Seminar: Valentin Buciumas (Pohang University of Science and Technology)
Title: Metaplectic Whittaker functions and quantum groups Abstract: In papers from around 2010, Yiannis Sakellaridis describes the space of unramified functions on the p-adic points of a spherical variety X in terms of the dual group of X (a reductive group). I will present a result which in some sense generalizes the one of Sakellaridis […]
