PhD Seminar — Summer Term 2018

This is the the website of the seminar of the PhD students of the Mathematics Department, research areas Algebra and Number Theory, Analysis and Differential Geometry and the RTG1670 of the University of Hamburg. If you want to subscribe to the mailing list please go to the mailing list's website.

This semester's topic is: Deformation Quantization and Factorization Algebras

The semester will roughly be divided into two parts. In the first part we will focus on deformation quantization, and in particular the following topics:
  • Motivation of deformation quantization from physics;
  • Basics of Poisson geometry;
  • Deformation of Poisson algebras, with examples;
  • Kontsevich's quantization formula, and a sketch of its proof;
The second part of the semester will be devoted to studying factorization algebras and how they show up in quantum field theories. We will discuss the following topics:
  • Motivation, definition and examples of factorization algebras;
  • Factorization algebras of observables;
  • Operations for factorization algebras;
  • Quantization

The seminar takes place on Mondays, 14:00 - 15:00 in room 1643 (Geomatikum)

Sessions this term: TBD
