Math Event: Algebraic Geometry Seminar: Ziquan Zhuan - Stable degeneration of symplectic singularities and Kaledin's conjecture
Time: 4:00 PM - 5:00 PM
Location:
Speaker: Ziquan Zhuan
Abstract: A normal variety has symplectic singularities if its smooth part carries a symplectic 2-form that extends to a regular 2-form on a resolution. Kaledin conjectured that every symplectic singularity is formally conical. Namely, it is formally isomorphic to a symplectic singularity with a good torus action. I will explain a proof of this conjecture, using tools from K-stability such as stable degeneration of singularities. Based on joint work with Chenyang Xu (with help from Henri Guenancia).

Math Event: Colloquium: Roger Van Peski - Eigenvalues of p-adic random matrices and zeros of p-adic L-functions
Time: 2:15 PM - 3:15 PM
Location: Math Tower P-131
Speaker: Roger Van Peski
Abstract: Abstract: The asymptotic behavior of eigenvalues of real and complex random matrices governs (in many precise senses) a variety of objects in physics and mathematics, famously including the distribution of zeros of the Riemann zeta function and related L-functions. The eigenvalues of p-adic random matrices were similarly predicted by Ellenberg-Jain-Venkatesh (2011) to model zeros of p-adic L-functions. However, random matrix theory over the p-adic numbers is much less developed, and many basic eigenvalue statistics have still not been computed. This talk will explain recent results on eigenvalues of p-adic random matrices, including a surprising Jacobi theta function formula for the pair correlation, the precise conjectures on zeros of p-adic L-functions which come from these, and numerical tests of these conjectures. Based on joint work with J. Shen, https://arxiv.org/abs/2601.06283, and work in preparation with J. Shen and H. Knospe.
