The higher Du Bois and higher rational properties for isolated singularities
Robert Friedman, Radu Laza
Higher rational and higher Du Bois singularities have recently been introduced as natural generalizations of the standard definitions of rational and Du Bois singularities. In this…
Higher Du Bois and higher rational singularities
Robert Friedman, Radu Laza
We prove that the higher direct images of the sheaves of relative Kähler differentials are locally free and compatible with arbitrary base change for fla…
Deformations of some local Calabi-Yau manifolds
Robert Friedman, Radu Laza
We study deformations of certain crepant resolutions of isolated rational Gorenstein singularities. After a general discussion of the deformation theory, we specialize to dimension…
Deformations of singular Fano and Calabi-Yau varieties
Robert Friedman, Radu Laza
The goal of this paper is to generalize results concerning the deformation theory of Calabi-Yau and Fano threefolds with isolated hypersurface singularites, due to the first author…
