Abstract
We introduce a lifting property for local cohomology which leads to a unified treatment of the dualizing complex for at morphisms with semi-log-canonical, Du Bois or F-pure fibers. As a consequence, we obtain that in all three cases, the cohomology sheaves of the relative dualizing complex are at and commute with base change. We also derive several consequences for deformations of semi-log-canonical, Du Bois and F-pure singularities.
