Theses


Summer Semester 2020

  • Geometry Oberseminar
    Information on the Geometry Oberseminar can be found
    here.

  • Topology II
    will be the continuation of last semester's topology course. Topics will include cohomology, product structures, and duality for manifolds. More details are to follow.
    It is unclear at this point if this lecture will be held in person or online. Details will be announced here as soon as they are known
  • Seminar Geometric Group Theory
    This is a seminar aimed at any students who know basic topology and are interested in learning the basics of geometric group theory, one of my areas of research. Details on the seminar can be found here.
    Most likely this seminar will be held online (via zoom). Details will be announced here. As there will not be a usual first meeting in person, I ask you to register by email.
  • Seminar Curve Graphs and Hierarchies
    This is an advanced seminar aimed at students who know some basics about mapping class groups of surfaces, and are interested in learning tools from active research in these groups. Details on the seminar can be found here.
    Most likely this seminar will be held online (via zoom). Details will be announced here. As there will not be a usual first meeting in person, I ask you to register by email.

Winter semester 2019/20


Summer semester 2019

  • Geometry Oberseminar
    Information on the Geometry Oberseminar can be found here.

  • Riemannian Geometry
    This is a continuation of the differentiable manifolds course from last semester.

    The Nachklausur will be on October 4, 9-12, in room B138.

    For preparation, here is the original exam, with solution sketches.

    A script, containing the material covered up to now, can be found here. An outlook containing material that will be covered in upcoming lecture is here. This latter document is likely full of mistakes and incomplete.

    Problem sets:

  • Mapping class groups and low-dimensional topology
    This is an introduction to mapping class groups and related topics. I will assume familiarity with manifolds, but not much more.

    A preliminary script, containing new material and (slowly) also older material, can be found here

    Tuesday, June 15, from 2-4, in room B252 there will be an extra class (since the course had to be cancelled once).

Winter semester 2018/19

  • Differentiable Manifolds

    The Einsicht (a chance to look at your exam) will happen Thursday, May 2, 10-11 am in room B336 (the TMP meeting room).

    The lecture script can be found here.
    The notes for Robert Hellings lectures are here: Physics and exterior derivatives, More on connections, and physics outlook.
    This is a brief summary of important homework problems (and a solution of problem 10.2c).
    A solution to Problems 2 and 3 of the exam. Solutions for the make-up-exam will be published shortly.
