Lyubeznik’s Invariants for Cohomologically Isolated Singularities
نویسنده
چکیده
In this note I give a description of Lyubeznik’s local cohomology invariants for a certain natural class of local rings, namely the ones which have the same local cohomology vanishing as one expects from an isolated singularity. This strengthens our results of [BB04] while at the same time somewhat simplifying the proofs. Through examples I further point out the bad behavior of these invariants under reduction mod p.

Moduli of Isolated Hypersurface Singularities
It was shown by J.N. Mather and S.S.-T. Yau that an isolated complex hypersurface singularity is completely determined by its moduli algebra. In this article it is shown, for the simple elliptic singularities, how to construct continuous invariants from the moduli algebras and, hence, associate invariants to the singularities themselves.

S OF SHORT COMMUNICATIONS AND POSTERS Alonso González, Clementa Title: Topological invariants of singularities of real vector fields in dimension three. Abstract: We give topological invariants for a wide class H(π) of absolutely isolated singularities of three-dimensional vector fields. Our invariants are complete once the desingularization morphism π is fixed. They are obtained in terms of a ...

In this paper we develope a Morsification Theory for holomorphic functions defining a singularity of finite codimension with respect to an ideal, which recovers most previously known Morsification results for non-isolated singularities and generalise them to a much wider context. We also show that deforming functions of finite codimension with respect to an ideal within the same ideal respects ...
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...
