**Algebraic Geometry 3: Toric Varieties**

Toric varieties are a class of algebraic varieties, which can be constructed and studied via combinatorial methods. They serve as concrete examples to study and to test conjectures.

**Prerequisites:**

Algebraic Geometry 2 (SS 2018) by Prof. Jan Kohlhaase, see: AlgGeo2

**Content:**

We will mostly follow the rst three chapters of Fulton's book, which give the basics of toric varieties. If time permits, we will also study a few specific topics.

**Time and place:**

Vorlesung: Monday 10-12 WSC-S-3.14

Vorlesung: Wednesday 10-12 WSC-S-3.14

Übung: Tuesday 8-10 WSC-N-U-4.03

Comment: This is a comprehensive book on Toric varieties.

Comment: Toroidal embeddings are varieties which look like a toric variety locally.

Comment: Toric varieties and toroidal embeddings are important examples of log schemes. In fact, log schemes are closely related to toric schemes locally. More precisely, the very important notion of chart of log scheme is modeled on toric scheme.
