OWR: Universal central extensions of gauge groups

TL;DR

This paper discusses the implications of previous work on the second Lie algebra cohomology of equivariant map algebras and loop algebras, focusing on universal central extensions of gauge groups.

Contribution

It provides insights into the structure of universal central extensions of gauge groups and their relation to Lie algebra cohomology.

Findings

Connections to universal central extensions

Abstract

We briefly indicate some implications of [1] for the second Lie algebra cohomology of equivariant map algebras and (twisted multi) loop algebras.
