SUMMARY:Karim Adiprasito\, Ehrhart theory revisited: Algebraic aspects\, unimodality and more
DESCRIPTION:Ehrhart theory is the study of lattice polytopes\, specifically aimed at understanding how many lattice points are inside dilates of a given lattice polytope\, and the study has a wide range of connections ranging from coloring graphs to mirror symmetry and representation theory. Recently\, we introduced new algebraic tools to understand this theory\, and resolve some classical conjectures. I will explain the combinatorial underpinnings behind two of the key techniques: Parseval identities for semigroup algebras\, and the character algebra of a semigroup.
