On the transitivity of the group of orbifold diffeomorphisms
Federica Pasquotto, Thomas O. Rot
Consider a connected manifold of dimension at least two and the group of compactly supported diffeomorphisms that are compactly supported isotopic to the identity. This group acts…

Degree theory for orbifolds
Federica Pasquotto, Thomas O. Rot
In [3] Borzellino and Brunsden started to develop an elementary differential topology theory for orbifolds. In this paper we carry on their project by defining a mapping degree for…

Homotopy classes of proper maps out of vector bundles
Thomas O. Rot
In this paper we classify the homotopy classes of proper maps , where is a vector bundle over a compact Hausdorff space. As a corollary we compute the…
