Welcome!

Part of me, holding my dog.
Part of me, holding my dog.

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

My main interests are in:

  • dynamical systems: foundations, stability and bifurcation,
  • in particular: various classes of delay equations,
  • related aspects of linear algebra and functional analysis,
  • related aspects of symbolic-numerical computation.

I consider myself competent in Fortran 90-2003, C (but not C++), MATLAB and Maple.
Also, I enjoy Emacs Lisp, but mostly just to customize my editor.

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

Formulas in $\LaTeX$ were processed using the QuickLaTeX plugin and, more recently, the MathJax engine. These are both great projects and they each deserve a look.
