# Master Seminar: Geometry of moduli stacks

**Termin**: **Freitag 14-16** Uhr in WSC-S-U-3.01.

**Dozenten** J. Heinloth.

In both complex and algebraic geometry it is of fundamental interest to construct and study parameter spaces of geometric objects like vector bundles, (elliptic) curves etc. Those *moduli spaces* are usually not complex manifolds or algebraic varieties themselves but what one calls a *stack* (german: *Stack*, french: *champ*). We have the following hierarchy:

(analytic/algebraic spaces) ⊂ (analytic/algebraic stacks)

Aim of the seminar is to learn what these are by studying prototypical examples of stacks like

(1) stacky curves

(2) moduli spaces of elliptic curves

(3) moduli spaces of vector bundles.

In order to attend the seminar, you should be familiar with either complex or algebraic geometry as covered by a two semester course. Depending on the background of the participants the seminar will be either more algebraic or more analytic/topoogical. The program discussion takes place in room

**WSC-S-3.14 on Tuesday February 11 at 15:00.**
