## Floris Takens Seminar

The seminar of our group Dynamical Systems, Geometry and Mathematical Physics is named after our founding father Floris Takens (1940-2010) whose research has been very influential on our work. This is also reflected in the spirit of our group seminar.

The painting of Floris Takens on the right is by Jacqueline Kasemier (Usquert, 2005).
