On the Virtual Euler Characteristic of the Moduli Space of Stable Pairs on Surfaces

Algebraic Geometry 2025-05-30 v1

Abstract

We study the stable pair theory on toric surfaces and determine the virtual tangent space over the fixed point loci. Further, we present a program to compute the virtual Euler characteristic, illustrated by the case of the projective plane. As an application, conjectures regarding rationality and symmetry are supported by verification of a special case.
