School Quantum Geometry

Third Erlangen Fall School on Quantum Geometry

Department Mathematik, Friedrich-Alexander-Universität Erlangen-Nürnberg

Erlangen, September 15-18 2014

The Erlangen Fall Schools on Quantum Geometry are a series of interdisciplinary schools on mathematical physics topics surrounding geometry and quantisation. They address postdocs and PhD students from both subjects and aim to provide an overview as well as an in-depth understanding of current research topics at the interface of mathematics and physics.

Courses

The Third Erlangen Fall School on Quantum Geometry involves three intensive lecture series. Each lecture series consists of approximately 6 hours of lectures as well as problem and discussion sessions. They are aimed at a mixed audience of mathematicians and physicists and are accessible to PhD students and postdocs.

  • Teichmüller Theory

    Vladimir Fock, Université de Strasbourg, IRMA

    Abstract:
    The main aim of the course is to present a combinatorial approach to Teichmüller spaces of complex structures on Riemann surfaces. We will give an explicit coordinate description of this space using hyperbolic geometry and then proceed to its quantization using quantum dilogarithm. We will also discuss relations of Teichmüller spaces to cluster varieties, Dehn invariant and Bloch group, higher Teichmüller spaces. If time permits the relation to integrable systems will also be discussed. Knowledge of these subjects is not assumed. On the contrary, we hope that the course will serve as an introduction to these branches of mathematics.

    A significant part of the course can be found in the following articles:

      1. V.V. Fock, A.B. Goncharov, Dual Teichmüller and lamination spaces. arXiv:math/0510312
      2. L.Chekhov, V.V.Fock, Quantum Teichmüller space, arXiv:math/9908165

     

    Elementary knowledge of hyperbolic geometry in two and three dimension and of the notion of Poisson structure is recommended. We also recommend to look through the definitions of Weil representation, Dehn invariant and (Liouville) integrable system.

     

  • Deformations of Operator Algebras and the Construction of Quantum Field Theories

    Gandalf Lechner, Universität Leipzig

 

  • Geometric Quantization

    Gijs Tuynman, Université Lille 1

    Abstract:
    In this course I intend to describe the geometric quantization procedure in all its details, starting with prequantization and going from to half-density quantization to half-form quantization. I will try to emphasize the why of all constructions, starting with the initial motivation from physics for this procedure. I will also give explicit formulas that permit to compute examples. Depending upon on time I will sketch most/some of the proofs.

    In my course I will rely upon basic knowledge concerning symplectic mechanics, Lie groups and fibre bundles (but just the basics). The following references contain certainly (infinitely) much more than I will need. In any case, I will recall (if necessary) what I need.
