Local equivalence of symmetric hypersurfaces in
Martin Kolar
The Chern-Moser normal form and its analog on finite type hypersurfaces in general do not respect symmetries. Extending the work of N. K. Stanton, we consider the local equivalence…

Generalized models and local invariants of Kohn-Nirenberg domains
Martin Kolar
We give an explicit verifiable characterization of weakly pseudoconvex but locally nonconvexifiable hypersurfaces of finite type in dimension two. It is expressed in terms of a gen…
