Title: Log-concave inequalities for posets

Abstract: The study of log-concave inequalities for combinatorial objects
has seen much progress in recent years. One such progress is the solution
to the strongest form of Mason's conjecture (independently by Anari et. al.
and  Brándën-Huh) that the f-vectors of matroid independence complex is
ultra-log-concave. In this talk, we discuss a new proof of this result
through linear algebra, and discuss generalizations to greedoids and posets.
This is a joint work with Igor Pak. This talk is aimed at a general
audience.
