Observables in the equivariant A-model
Full text linkWe discuss observables of an equivariant extension of the A-model in the
framework of the AKSZ construction. We introduce the A-model observables, a
class of observables that are homotopically equivalent to the canonical AKSZ
observables but are better behaved in the gauge fixing. We discuss them for two
different choices of gauge fixing: the first one is conjectured to compute the
correlators of the A-model with target the Marsden-Weinstein reduced space; in
the second one we recover the topological Yang-Mills action coupled with
A-model so that the A-model observables are closed under supersymmetry.Comment: 16 pages; minor correction
