Geometric Quantization

This lecture course (2 hours a week, Master, V5D3) will explain geometric efforts to "quantize a classical system". Nevertheless, we will only briefly talk about the physical background, but will use this theory as a tool to understand more about Spinc manifolds with a Lie group action. For this we will define the Spinc quantization which is the equivariant index of a Dirac operator

We will start by explaining the background material (Spinc structures, Dirac operators, equivariant cohomlogy) and then prove and discuss to remarkable theorems:

  • Additivity under cutting: We cut an manifold along a hypersurface into two manifolds (where we "destroy" the boundary by a special construction), then the resulting quantizations add up to the original one.
  • Quantization commutes with reduction: With the help of a hypersurface, we can construct a reduced manifold of dimension 2m-2. Und sensible assumptions on the hypersurface, this reduction procedure commutes with the quantization.

Prerequisites: "Globale Analysis I", basic knowledge of vector bundles, principal bundles and connections

Useful techniques (knowledge not assumed): Spinc structures, Dirac operators, Representations of compact Lie groups

Furthermore, you will learn something about applications of the Atiyah-Singer-index theorem and the Lefschetz fixed point formula (we do not assume prior knowledge about these topics either; instead we will discuss ideas and applications while giving proper definitions but nearly no proofs).
