Deformations of objects in $n$-categories

Abstract

In this paper, we prove that the deformation theory of an object in an nn-category is controlled by the its nn-fold endomorphism algebra. This recovers Lurie's results on deforming objects and categories. We also generalize a previous result by Blanc et al. on deforming a category and an object simultaneously to the case of nn-categories.
