Fields Special Presentation
Time: 14:30
Speaker: Fields (University of Toronto) Title: "Quantitative Information Security Specialist Program" Room: WSC 240 Abstract: This training program is specifically designed for graduate students and recent PhDs in mathematics or related fields, who are looking to transition to work in the information security industry after graduation. Geometry and Combinatorics
Time: 15:30
Speaker: Daniel Bath (KU Leuven) Title: "Bernstein-Sato polynomials for hyperplane arrangements of rank 3" Room: MC 108 Abstract: The Bernstein-Sato polynomial (and its roots) are important invariants of hypersurface singularities. It is a Rosetta Stone: it seems most singularity data lies within, if only one could decode it. Unfortunately, after 50 years actual computations remain scarce. I will give a formula for the roots of Bernstein-Sato polynomials of hyperplane arrangements in three variables. It turns out all but one root is determined by the combinatorics, and the outlier root is determined by simple algebraic data. Time permitting I will connect this non-combinatorial root to the realization space of the underlying matroid. |
