Contribution to Research Areas

Research Area A
I am interested in stratifolds, a generalization of manifolds which I introduced. These are differential topological objects and so (besides topological applications) one can try to prove analytical statements for stratifolds. In this direction I studied de Rham cohomology for stratifolds [1], [2].
Another related research concerns the construction of quantum field theories [3].
