Abstract: We show that a cosection of the obstruction sheaf of a perfect obstructiontheory localizes the virtual cycle to the non-surjective locus of thecosection. We give algebraic constructions of localized Gysin maps andlocalized virtual cycles. Various applications of these constructions arediscussed.
