GW invariants and invariant quotients

M. Halic[1]

(1) Ruhr-Universit├Ąt Bochum, Germany

Given a complex, projective variety and a connected, reductive group acting on it, we investigate the relationship between the Gromov-Witten invariants of the variety and those of its invariant quotient for the group action. Certain so-called Hamiltonian invariants naturally appear in the context.

Keywords: Gromov-Witten invariants, group actions, Hamiltonian invariants
