Virtual Residue and an integral formalism

Algebraic Geometry 2018-01-08 v3

Abstract

We generalize Grothendieck's residues ResψsRes\frac{\psi}{s} to virtual cases, namely cases when the zero loci of the section ss has dimension larger than the expected dimension(zero). We also provide an exponential type integral formalism for the virtual residue, which can be viewed as an analogue of the Mathai-Quillen formalism for localized Euler classes.
