The focuses of the Institute of Mathematical Stochastics lie in the analysis of complex stochastic systems which appear in numerous fields of natural and social sciences. Amongst others the following topics are of special interest: complex networks, branching processes, percolation theory, renewal theory, statistical mechanics, random matrices, random analytic functions, extreme value theory, large deviations, stochastic approximation, stochastic geometry, optimal transport, financial and actuarial mathematics.


A course on Probability Theory that provides a deep knowledge on the following subjects:

Measure and integration, stochastic independence, product spaces, Markov-kernels, 0-1 laws, martingales, laws of large numbers, weak convergence, central limit theorem.

These topics can be found in the book Probability Theory of Prof. Dr. Achim Klenke.
