A deformation of instanton homology for webs

Peter B Kronheimer and Tomasz S Mrowka

Geometry & Topology 23 (2019) 1491–1547
Abstract

A deformation of the authors’ instanton homology for webs is constructed by introducing a local system of coefficients. In the case that the web is planar, the rank of the deformed instanton homology is equal to the number of Tait colorings of the web.
