Universal Central Extensions

The following is an account, self-contained and essentially expository, of the general theory of universal central extensions of groups with applications to some important classes of groups: perfect groups, abelian groups and connected Lie groups. The notation is occasionally different from that in the text — this should not cause any confusion.

Universal Central Extensions

In this paper, we study the universal central extension of a Lie–Rinehart algebra and we give a description of it. Then we study the lifting of automorphisms and derivations to central extensions. We also give a definition of a non-abelian tensor product in Lie–Rinehart algebras based on the construction of Ellis of non-abelian tensor product of Lie algebras. We relate this non-abelian tensor product to the universal central extension.
