Canonical sheaves at isolated canonical Gorenstein singularities
Jean Ruppenthal
It is well known that the Grauert-Riemenschneider canonical sheaf of holomorphic square-integrable -forms is a central tool in -theory for the $\overline\pa…
Estimates for the -equation on canonical surfaces
Mats Andersson, Richard Lärkäng, Jean Ruppenthal +2
We study the solvability in of the -equation in a neighborhood of a canonical singularity on a complex surface, a so-called du Val singularity. We get a quite c…
Chern forms of singular metrics on vector bundles
Richard Lärkäng, Hossein Raufi, Jean Ruppenthal +1
We study singular hermitian metrics on holomorphic vector bundles, following Berndtsson-P{ă}un. Previous work by Raufi has shown that for such metrics, it is in general not possibl…
Koppelman formulas on affine cones over smooth projective complete intersections
Richard Lärkäng, Jean Ruppenthal
In the present paper, we study regularity of the Andersson-Samuelsson Koppelman integral operator on affine cones over smooth projective complete intersections. Particularly, we pr…
-sheaves of holomorphic functions and -forms on complex spaces with isolated singularities
Jean Ruppenthal
Let be a Hermitian complex space of pure dimension with isolated singularities. In the present paper, we give a natural resolution for the canonical sheaf of square-integra…
Parabolicity of the regular locus of complex varieties
Jean Ruppenthal
The purpose of this note is to show that the regular locus of a complex variety is locally parabolic at the singular set. This yields that the regular locus of a compact complex va…
