Internet Seminar 2020/21: C* algebras and dynamics
The internet seminar on evolution equations has been organized every year since 1997 by several working groups in Germany, Italy, Hungary and the Netherlands. It was founded by the functional analysis group in Tübingen. The participants are advanced master students and Ph.D students. From October to February the participants obtain weekly study material at a website. They are supervised by local coordinators at their university (in Karlsruhe: P.Kunstmann and R. Schnaubelt). From March to June they work in (internationally mixed) small groups on a project and report on it in June at the final workshop. This year's workshop takes place in Wuppertal from 6 to 12 June 2021.
This internet seminar is organised by Christian Budde (Potchefstroom) and Moritz Weber (Saarbrücken). It is concerned with C* algebras, spectral theory on banach algebras and dynamical systems on C* algebras.
Basic knowledge in functional analysis and complex analysis is stringly recomended. One can register for the internet seminar at its web page, where further information is given. See also this description of the course. In Karlsruhe we will discuss the weekly material in the lecture (or better: the reading course) C*-Algebren und Dynamik.
You can find the history of this series of seminars on the internet seminar web site of our group.
CRC 1173 Wave phenomena: analysis and numerics
In the second funding period of the Collaborative Research Centre 1173 (07/19 - 06/23), I am speaker of the integrated research group and principal investigator of the projects
- A4: Time integration of Maxwell equations (with M. Hochbruck),
- A5: Qualitative behavior of nonlinear Maxwell equations.
In the first funding period (07/15 - 06/19) I was also a principal investigator of the projects B2: Dispersion Management (with D. Hundertmark) and B5: Biharmonic wave maps (with T. Lamm).
- Qualitative properties of evolution equations, in particular of hyperbolic and parabolic partial differential equations:
- Wellposedness and regularity
- Asymptotic properties of solutions: global existence versus blow-up, stability, convergence, invariant manifolds.
- Error analysis for numerical schemes of time integration.
- Lp-regularity of linear parabolic partial differential equations with unbounded or degenerate coefficients.
- Recent research focus: Maxwell equations.
- Control theory.
- Stochastic evolution equations.
- Non-autonomous linear evolution equations: asymptotic theory (in particular, exponential dichotomy), existence theory. In this context: evolution semigroups and operator sum method.
- Spectral and operator theory.

Euro-Maghrebian Workshops on Evolution Equations
Since the late 90s the Euro-Maghrebian Workshops on Evolutions Equations have been organized biannually by working groups in Germany, Italy, and France, as well as Morocco, Algeria and Tunisia. This series was started in 1999 by Rainer Nagel and Abdelaziz Rhandi Marrakesh. In these workshops we put a special emphasis on mini courses about recent topics in evolution equations. An overview of these meetings is given on this website.
