A momentum map for the Heisenberg group (2308.01866v2)
Published 3 Aug 2023 in math.SG
Abstract: These notes treat a momentum map associated to the Heisenberg group. We classify the coadjoint orbits of the Heisenberg group and show that the cocycle associated to the momentum map becomes a value of the modulus of a coadjoint orbit. We give a representation theoretic description of this modulus.
