Homotopy 2-regular mappings whose inverses are open 3-cells
Homotopy Classification of Equivariant Regular Sections.
Homotopy Decompostitions of Equivariant Function Spaces.
Homotopy negligible subsets of bundles
Homotopy theory of Hopf Galois extensions
We introduce the concept of homotopy equivalence for Hopf Galois extensions and make a systematic study of it. As an application we determine all -Galois extensions up to homotopy equivalence in the case when is a Drinfeld-Jimbo quantum group.
