About me

Me, hiding behind my dog.

Me, hiding behind my dog.

My name is Sebastiaan Janssens and I work in mathematics under supervision of my PhD advisors O. Diekmann and S.A. van Gils and also in cooperation with Yu.A. Kuznetsov at Utrecht University and the University of Twente in The Netherlands.

My interests are in dynamical systems from a functional analysis viewpoint, and vice versa. At the moment, the focus is on:

  • semiflows, stability and bifurcation for various classes of delay equations,
  • dynamical systems on metric spaces, and spaces of measures in particular.

Delay equations is also the eponym of a domain that I have registered for the plan of creating a cooperative wiki about aspects of theory and examples of delay equations. If you have expertise and would like to cooperate, consider letting me know.
