Contents
Toric varieties form an important class of examples of algebraic varieties which can be described
purely in terms of convex geometry. The connection between convex geometry and algebraic geometry
turns out to be an essential tool to solve difficult problems either in convex geometry or in
algebraic geometry. We will follow the book 'Combinatorial Convexity and Algebraic Geometry' by
Ewald. In the first part of the seminar we will focus on convex geometry. We will introduce cones,
dual cones, monoids, fans, etc. and study their basic properties along with several examples. For
this part of the seminar a solid knowledge of linear algebra (LA 1+2) and analysis (Analysis 1+2) is
required. In the second part of the seminar we apply the notions from convex geometry introduced in
the first part to algebraic geometry by introducing the class of toric varieties. We will see how
algebro-geometric statements about toric-varieties can be translated into problems of convex
geometry which are sometimes easier to solve. The second part of the seminar is particularly
recommended to students interested in algebraic geometry. It requires basic knowledge in algebraic
geometry which can be acquired for instance by attending the course 'Algebraic geometry I'
simultaneously.
