Applied Mathematics Seminar

Each semester we have our weekly seminar. Talks are given by members of our math department, reporting on their recent research, and guests of our research groups.

Everybody is welcome to join!

For further information please contact Johannes Maly via johannes(dot)maly(at)ku(dot)de.
