Abstract

Given a 4d N=2{\mathcal N}=2 supersymmetric theory with an N=(2,2){\mathcal N}=(2,2) supersymmetric surface defect, a marginal perturbation of the bulk theory induces a complex structure deformation of the defect moduli space. We describe a concrete way of computing this deformation using the bulk-defect OPE.
