S.G. Janssens, On a Normalization Technique for Codimension Two Bifurcations of Equilibria of Delay Differential Equations, Master Thesis, Utrecht University, 2010.
Under supervision of Yu.A. Kuznetsov, cosupervised by O. Diekmann.

Original version in the university’s repository from Autumn 2010.
Two journal articles based in part on this work are in preparation.
The newest versions of the free software package DDEBIFTOOL contain an implementation for the case of delay differential equations with finitely many constant delays,
\[
\dot{x}(t) = f(x(t), x(t – \tau_1),\ldots,x(t – \tau_m),\alpha)
\]
where $x(t) \in \mathbb{R}^n$, $\alpha \in \mathbb{R}^p$ is a parameter vector and $0 < \tau_1 < \ldots < \tau_m < \infty$. This work was done in collaboration with M.M. Bosschaert, former M.Sc student of Yuri Kuznetsov, now at Hasselt University.
