Topological group cohomology of Lie groups and Chern-Weil theory for compact symmetric spaces

Christoph Wockel

In this paper we analyse the topological group cohomology of finite-dimensional Lie groups. We introduce a technique for computing it (as abelian groups) for torus coefficients by…

A Cocycle Model for Topological and Lie Group Cohomology

Friedrich Wagemann, Christoph Wockel

We propose a unified framework in which the different constructions of cohomology groups for topological and Lie groups can all be treated on equal footings. In particular, we show…

Topological Group Cohomology with Loop Contractible Coefficients

Martin Fuchssteiner, Christoph Wockel

We show that for topological groups and loop contractible coefficients the cohomology groups of continuous group cochains and of group cochains that are continuous on some identity…

Making Lifting Obstructions Explicit

Karl-Hermann Neeb, Friedrich Wagemann, Christoph Wockel

If P \to X is a topological principal K-bundle and \hat K a central extension of K by Z, then there is a natural obstruction class δ_1(P) in \check H^2(X,\uline Z) in sheaf cohomol…

A Smooth Model for the String Group

Thomas Nikolaus, Christoph Sachse, Christoph Wockel

We construct a model for the string group as an infinite-dimensional Lie group. In a second step we extend this model by a contractible Lie group to a Lie 2-group model. To this en…

The Samelson Product and Rational Homotopy for Gauge Groups

Christoph Wockel

This paper is on the connecting homomorphism in the long exact homotopy sequence of the evaluation fibration , where is the gauge g…
