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. 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.

Via the menu at the top you find some information on my work, as well as my blog.

For formula typesetting I use the Simpe MathJax plugin. It enables MathJax in WordPress, so I can use $\LaTeX$ on my site.
GNU Fortran is an excellent free and open compiler supporting modern Fortran.

Convoy of hearses carrying victims of MH-17

On the 17th of July 2014 a total of 298 innocent people (passengers and crew) were killed above Eastern Ukraine when their civil aircraft was destroyed by a ground missile.

This mass murder and its aftermath continue to put the Russian government to shame. It will not be forgotten, nor forgiven.
