Active projects
Nonperturbative quantisation of gauge theories, noncommutative geometry and unification of the fundamental interactions
Jan Govaerts

Development of nonperturbative quantisation techniques of gauge theories (Yang-Mills, topological, gravity) and their application to particle physics and quantum field theory at finite temperature (in particular, within the context of superconductivity).
Exploration of the consequences of noncommutative geometry in the search for the unification of the fundamental interactions (M-theory and superstrings, quantum gravity).

Topology and Non-Perturbative Gauge Dynamics
Jan Govaerts

The connections between topology in space(time) and in field configuration space and the non-perturbative dynamics of general gauge theories, inclusive of mass generating mechanims, are being studied.
