June Huh

Wednesday April 20, 4:00pm-5:10pm
Padelford C-401

Pre-Seminar 3:30pm-3:55pm in PDL C-401

ABSTRACT

I will give an overview of the Hard Lefschetz theorems and the Hodge-Riemann relations in the theory of polytopes, complex manifolds, reflection groups, algebraic and tropical varieties. Several applications of elementary combinatorial nature will be introduced.
