In this paper we develop an abstract setup for hamiltonian group actions as follows: Starting with a continuous 2-cochain ω on a Lie algebra h with values in an h-module V , we associate subalgebras sp(h, ω) ⊇ ham(h, ω) of symplectic, resp., hamiltonian elements. Then ham(h, ω) has a natural central extension which in turn is contained in a larger abelian… (More)
