Quasi-periodic paths and a string 2-group model from the free loop group
Michael Murray, David Michael Roberts, Christoph Wockel
In this paper we address the question of the existence of a model for the string 2-group as a strict Lie-2-group using the free loop group (or more generally for compa…
Functorial aspects of the reconstruction of Lie groupoids from their bisections
Alexander Schmeding, Christoph Wockel
To a Lie groupoid over a compact base, the associated group of bisection is an (infinite-dimensional) Lie group. Moreover, under certain circumstances one can reconstruct the Lie g…
(Re)constructing Lie groupoids from their bisections and applications to prequantisation
Alexander Schmeding, Christoph Wockel
This paper is about the relation of the geometry of Lie groupoids over a fixed compact manifold and the geometry of their (infinite-dimensional) bisection Lie groups. In the first…
The Lie group of bisections of a Lie groupoid
Alexander Schmeding, Christoph Wockel
In this article we endow the group of bisections of a Lie groupoid with compact base with a natural locally convex Lie group structure. Moreover, we develop thoroughly the connecti…
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…
Integrating central extensions of Lie algebras via Lie 2-groups
Chenchang Zhu, Christoph Wockel
The purpose of this paper is to show how central extensions of (possibly infinite-dimensional) Lie algebras integrate to central extensions of étale Lie 2-groups. In finite dimensi…
