A Simple Characterization of Du Bois Singularities
We prove the following theorem characterizing Du Bois singularities. Suppose that Y is smooth and that X is a reduced closed subscheme. Let π : e Y → Y be a log resolution of X in Y that is an isomorphism outside of X. If E is the reduced pre-image of X in e Y , then X has Du Bois singularities if and only if the natural map ØX → Rπ∗ØE is a quasi-isomorphism. We also deduce Kollár’s conjecture ...
متن کاملThe Canonical Sheaf of Du Bois Singularities
We prove that a Cohen-Macaulay normal variety X has Du Bois singularities if and only if π∗ωX′(G) ≃ ωX for a log resolution π : X ′ → X , where G is the reduced exceptional divisor of π. Many basic theorems about Du Bois singularities become transparent using this characterization (including the fact that Cohen-Macaulay log canonical singularities are Du Bois). We also give a straightforward an...
متن کاملF-injective Singularities Are Du Bois
In this paper, we prove that singularities of F -injective type are Du Bois. This extends the correspondence between singularities associated to the minimal model program and singularities defined by the action of Frobenius in positive characteristic.
متن کاملRigid and Complete Intersection Lagrangian Singularities
In this article we prove a rigidity theorem for lagrangian singularities by studying the local cohomology of the lagrangian de Rham complex that was introduced in [SvS03]. The result can be applied to show the rigidity of all open swallowtails of dimension ≥ 2. In the case of lagrangian complete intersection singularities the lagrangian de Rham complex turns out to be perverse. We also show tha...
متن کاملContinuous Invariants of Isolated Hypersurface Singularities
is a finite-dimensional algebra depending only on the germ of V at the origin and is invariant under holomorphic change of coördinates. Remarkably, it was shown by Mather and Yau [4] that A completely determines the germ of V . Thus, one should be able to distinguish between biholomorphically inequivalent singularities on the basis of their corresponding moduli algebras. This was accomplished f...
