Universal Central Extensions of Gauge Algebras and Groups

Christoph Wockel, Bas Janssens

Research output: Contribution to journalArticleAcademicpeer-review


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.
