My name is Sebastiaan Janssens. I am working on finishing my PhD in mathematics with O. Diekmann, S.A. van Gils and Yu.A. Kuznetsov at Utrecht University and the University of Twente in The Netherlands after being held back by health problems for longer periods of time.

I am interested in:

  • rigorous analysis of dynamical systems and their bifurcations,

  • in particular: various classes of delay equations,

  • linear algebra, functional- and numerical analysis.

My favorite programming language is modern Fortran. I wish I would have occasion to use it more often.

Most of my mathematical posts will feature small observations that do not fit easily in another form of publication. $\LaTeX$ formulas were processed using the QuickLaTeX plugin and, more recently, the MathJax engine. These are both great projects and they each deserve a look.
