Abstract

I will discuss various conjectures and theorems about extending (logarithmic) differential forms over singularities. The main issue at hand is to understand the difference between the sheaf of differentials and its reflexive hull. This is strongly related to extending differentials to exceptional sets of resolutions of singularities. I will also explain the motivation for such applications and a recent application of the results.
