Introduction
The Utrecht Dynamical Systems
Seminar is a monthly platform at the Utrecht Mathematical Institute
for the presentation and discussion of topics related to dynamical
systems theory with a focus on mathematical aspects but an open eye towards applications. The seminar
is organized by Heinz
Hanßmann and Sebastiaan Janssens.
It consists of a presentation of
approximately one hour, followed by discussion. Below you find the
schedule of upcoming talks.
Talks will be announced on the local Utrecht mailing lists. If you are not on this list but like to be included, please send a message.
Blackboard, overhead projector and
beamer are available, but unfortunately an internet connection is not
guaranteed. We are always interested in potential speakers! For
inquiries please contact one of the organizers.
