Fabian Hebestreit

During the winter term, i.e. September 2017 until March 2018, I am on leave from Bonn to be a visiting professor in the Differential Geometry group at the University of Augsburg substituting for Wolfgang Steimle. My new webpage is here.

Otherwise I am (and will be for the foreseeable future) a Post-Doc in the Topology group at the University of Bonn under the supervision of Wolfgang Lück.

Here is a rather lenghty CV and here there will soon be a statement of intent.

For the winter term the organisation of the Bonn topology seminar will be taken over by Christoph Winges .

Markus Land and I are the organisers of the second bavarian geometry and topology meeting to be held in Augsburg on december 14th and 15th.

Research Interests

Manifolds, mostly high dimensional! That is: Algebraic & Geometric Topology with a view towards Differential Geometry.
More specifically at the moment: Surgery theory and its applications to scalar curvature questions; cobordism categories and characteristic classes of manifold bundles; twisted bordism groups and parametrised homotopy theory

Publications and Preprints

In preparation

  • with M. Joachim: A factorisation of the twisted index map via parametrised homotopy theory.
  • with S. Stolz: Q_0-acyclic A(1)-modules and their Ext-groups.
  • with M. Land, G. Laures: Infinite loop space structures on G/Top.
  • with N. Perlmutter: Stable stability in odd dimensions.

Teaching

Next semester I will be teaching the lecture course Algebraic topology (in german), together with two seminars: The space of positive scalar curvature metrics, and Representation theory of finite groups (in german), all at the University of Augsburg.

This semester I am the teaching assistant of Saint Nikolaus for the lecture course Algebraic Topology II. More information can be found on the courses' websites.

Previously, I was the teaching assistant of Jens Franke for the lecture courses Linear algebra I, II and Introduction to algebra. More information (in german) can be found on the course's website.
