Universal Central Extensions of Gauge Algebras and Groups    [PDF]

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 universality of the corresponding central extension of
Lie algebras in a slightly more general setting.
