Block-G\"ottsche invariants from wall-crossing

Algebraic Geometry 2015-12-01 v2 Representation Theory

Abstract

We show how some of the refined tropical counts of Block and G\"ottsche emerge from the wall-crossing formalism. This leads naturally to a definition of a class of putative q-deformed Gromov-Witten invariants. We prove that this coincides with another natural q-deformation, provided by a result of Reineke and Weist in the context of quiver representations, when the latter is well defined.
