Abstract
In this note we gather together some diverse facts about the moment map for symplectic group actions and the corresponding reductions of the symplectic manifold on which the group acts. We also relate moment maps with the “character Lagrangian” so as to obtain “intertwining Lagrangians” for Hamiltonian group actions.
