Funktorialitäten für relative topologische Gruppen
Abstract: In this thesis, a right adjoint to the fibre product functor of the category of relative topological spaces with locally proper maps is constructed. After a discussion of its basic properties in chapter 3, in particular concerning its relation to the direct image functor of sheaves, it is used to formulate a version of Frobenius reciprocity in the context of continuous representations or, more generally, topological groups acting on relative topological spaces.
The definition of locally proper map has been introduced in [O. Schnürer, W. Soergel 2014]. It is a natural generalization of locally compact spaces to continuous maps. In the same vein, a separable or universally closed map is a generalization of Hausdorff spaces to continuous maps. Chapter 2 contributes strongly to the understanding of separable locally proper maps. The main result is a generalizition of the Alexandroff or one-point-compactification to continuous mappings: Every continuous map can be proprified by embedding the domain in a larger topological space and extending the map appropriately.
A corollary of this result is the characterization of separable locally proper maps as compositions of an open embedding and a separable proper map
