Fabian Hebestreit

I am an Assitant (Akademischer Rat auf Zeit) in the Topology group at the University of Bonn under the supervision of Wolfgang Lück.

Together with Markus Land I am organising a seminar on the Foundations of Hermitian K-theory within the eCHT framwork for fall 2021. During spring 2022 I will be visiting the Mittag-Leffler-Institute, Stockholm, as part of the program Higher algebraic structures in algebra, topology and geometry. Here is a CV.

Furthermore, I am currently the organiser of the Bonn topology seminar and organised the workshop Automorphisms of Manifolds with Wolfgang.

Research Interests

Manifolds, mostly high dimensional! That is algebraic & geometric Topology, homotopical Algebra and more specifically:
the homotopy theory of diffeomorphism groups and cobordism categories, and their relation to algebraic K- and L-theory, parametrised homotopy theory and its relation to operator algebras and positive scalar curvature

Publications and Preprints

Articles for Conference Proceedings

Teaching

Some lecture notes:

This term I am giving a seminar on Real Divisionalgebras (via Zoom).

Previously, I gave the lecture courses Algebraic and Hermitian K-theory, Higher categories and homotopical algebra (through Zoom) and Introduction to higher Categories together with Christoph Winges, was the teaching assistent of Daniel Kasprowski for the lecture course Topology II, and gave the course Mathematik für Geowissenschaftler II (in german). I ran seminars on Characteristic classes and Real Divisionalgebras (in german); I taught the lecture course Algebraic topology (in german), together with the two seminars The space of positive scalar curvature metrics, and Representation theory of finite groups (in german) at the University of Augsburg; I was the teaching assistant of Saint Nikolaus for the lecture course Algebraic Topology II, and that of Jens Franke for the lecture courses Linear algebra I, II and Introduction to algebra. More information can be found on the courses' websites.
