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…
(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…
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…
Universal Central Extensions of Gauge Algebras and Groups
Bas Janssens, Christoph Wockel
We show that the canonical central extension of the group of sections of a Lie group bundle over a compact manifold, constructed in [NW09], is universal. In doing so, we prove univ…
The diffeomorphism supergroup of a finite-dimensional supermanifold
Christoph Sachse, Christoph Wockel
Using the categorical description of supergeometry we give an explicit construction of the diffeomorphism supergroup of a compact finite-dimensional supermanifold. The construction…
