Abstract
Given a 4d \( \mathcal{N} \) = 2 superconformal theory with an \( \mathcal{N} \) = (2, 2) superconformal 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.
