Speaker: Bernard Sturmfels
Title: Kinematic Stratifications
Abstract: We study stratifications of regions in the space of symmetric matrices. These arise in particle physics and are related to matroids and Lorentzian polynomials. We characterize the kinematic strata, for massless and massive particles, without momentum conservation. This is recent work with Veronica Calvo and hadleigh Frost .

About the speaker
Bernd Sturmfels received doctoral degrees in 1987 from the University of Washington and the Technical University Darmstadt, and honorary doctorates from the universities of Frankfurt (2015) and Bern (2023). After postdoctoral years in Minneapolis and Linz, he taught at Cornell University, before joining UC Berkeley in 1995, where he served as Professor of Mathematics, Statistics and Computer Science. Since 2017 he is a director at the Max-Planck Institute for Mathematics in the Sciences, Leipzig. In 2018 he became Honarary Professor at Technical University Berlin and University of Leipzig. His awards include a David and Lucile Packard Fellowship, a Humboldt Senior Research Prize, the SIAM von Neumann Lecturership, the Sarlo Distinguished Mentoring Award, and the George David Birkhoff Prize in Applied Mathematics. He is a fellow of the AMS and SIAM, and a member of the Berlin-Brandenburg Academy of Sciences. In 2022 he spoke at the International Congress of Mathematicians. Sturmfels mentored 65 doctoral students and countless postdocs, and he authored 12 books and 310 research articles, in combinatorics, commutative algebra, algebraic geometry, and their applications to fields like statistics, optimization, computational biology, and fundamental physics.
