Abstract

I will give an introduction to higher-order versions of the classical notions of Du Bois and rational singularities and I will discuss an invariant that governs these notions for local complete intersections. This is based on joint work with Qianyu Chen, Bradley Dirks, Sebastian Olano,and Mihnea Popa.
