German title
Wellengleichungen auf lorentzschen Mannigfaltigkeiten und Quantisierung

Contents
The main concern of the seminar is to solve geometrically motivated hyperbolic partial differential equations on curved backgrounds. The simplest example is the wave equation on (flat) $\mR^n$ whose solution will be the starting point of the seminar. These solutions can be used to iteratively construct solutions on curved spacetimes, i.e. Lorentzian manifolds. As soon as we have solved these equations, we will construct natural $C^*$-algebras to a given space-time which is a key step in the quantization of fields in physics, although the seminar is purely of a mathematical nature. We follow a book by Bär, Ginoux and Pfäffle which is self-contained to a very large degree and didactically very efficient. More information may be found in the program of the seminar which is available on the web page of the seminar, linked below.

Literature

C. Bär, N. Ginoux, F. Pfäffle. Wave Equations on Lorentzian Manifolds and Quantization, ESI Lectures in Mathematics and Physics, EMS. Available as E-Book in our library.
From a UR computer or via VPN the book can be downloaded at https://doi.org/10.4171/037.
Further literature is given in the program of the seminar, see below.

Recommended previous knowledge
The seminar addresses, in particular, to students who have followed my lecture about differential geometry II in the summer term 2021. Students with knowledge of differential geometry I might follow as well, if they are willing to read a bit of additional literature.
Necessary

Good knowledge about differential geometry as e.g. taught in "Differential geometry I".
Some basic knowledge about Lorentzian manifolds or willingness to read into this.

Helpful (can also be learnt within the seminar)

Improved understanding of Lorentzian manifold, e.g. de (Anti-) deSitter space
Basic knowledge about hyperbolic partial differential equations
Basic knowledge about C^*-algebras
Basic knowledge about quantization
