Seminar
The UHH dynamical systems seminar meets roughly every week to discuss all aspects of dynamical systems, from theoretical analysis in discrete and continuous systems to applications in pattern formation, climate, biology and more. Talks are announced via an email group. If you would like to find out more, please email Prof. Dr. Jens Rademacher or Dr. Roland Welter.
