When differential equations were invented one used to (try to) find single solutions to given initial conditions. Nowadays one is increasingly interested in the global properties of the system: What are the relations between the solutions ? Are there classes of solutions with special properties ? It is a question of major interest, whether small perturbations have little influence on the global dynamics of the system or cause dramatic changes (structural stability, bifurcation).
It is possible to roughly divide the subject of my papers into three groups, so click on rigid body, resonant oscillators or bifurcations for more details. Inevitably, papers of one group may use examples or results from another group, and you may find a list of all my available preprints up to 2004 in the README file of my directory. For preprints from 2005 onwards see the list of Preprints of the Department of Mathematics. Alternatively, you can browse through MathSciNet or the MATH database (if you have access to these).
