Description

Toric varieties are geometric objects defined combinatorially, much like CW complexes in topology. They can be used to study geometrically combinatorial objects like semigroups, cones, polytopes or simplicial complexes. In Algebraic Geometry, toric varieties are a rich source of explicit examples, a good testing ground for gaining intuition for open problems.

The first part of this course is a general introduction to toric varieties. We assume basic knowledge of Algebraic Geometry.

The second part tours several topics of birational geometry, in the special case of toric varieties. The goal is to construct many explicit examples: of singularities, polarized varieties, and varieties of K-pure type (Fano, Calabi-Yau, canonically polarized). We assume basic knowledge of Birational Geometry.

We also present the combinatorial counterpart of part two, essentially criteria to construct central lattice points in convex sets.

  • The birational geometry of matroids

    AbstractIn this talk, I will consider isomorphisms of Bergman fans of matroids. Motivated by algebraic geometry, these isomorphisms can be considered as matroid analogs of birational maps. I will introduce Cremona automorphisms of the coarsest fan structure. These produce a class of automorphisms which do not come from automorphisms of the underlying matroid. I will then explain that the automo...
