Low-dimensional Singularities with Free Divisors as Discriminants
Ragnar-Olaf Buchweitz, Wolfgang Ebeling, Hans-Christian Graf v. Bothmer
We present versal complex analytic families, over a smooth base and of fibre dimension zero, one, or two, where the discriminant constitutes a free divisor. These families include…
The global decomposition theorem for Hochschild (co-)homology of singular spaces via the Atiyah-Chern character
Ragnar-Olaf Buchweitz, Hubert Flenner
We generalize the decomposition theorem of Hochschild, Kostant and Rosenberg for Hochschild (co-)homology to arbitrary morphisms between complex spaces or schemes over a field of c…
Global Hochschild (co-)homology of singular spaces
R. -O. Buchweitz, H. Flenner
We introduce Hochschild (co-)homology of morphisms of schemes or analytic spaces and study its fundamental properties. In analogy with the cotangent complex we introduce the so cal…
A comparative study of disc-planet interaction
M. de Val-Borro, R. G. Edgar, P. Artymowicz +20
We perform numerical simulations of a disc-planet system using various grid-based and smoothed particle hydrodynamics (SPH) codes. The tests are run for a simple setup where Jupite…
Class and rank of differential modules
Luchezar L. Avramov, Ragnar-Olaf Buchweitz, Srikanth Iyengar
A differential module is a module equipped with a square-zero endomorphism. This structure underpins complexes of modules over rings, as well as differential graded modules over gr…
