Three deformation functors for associative algebras
Frank Schuhmacher
We show that three deformation functors (deformations of the product, flat deformations and deformations of the relations) assigned to an associative algebra are naturally isomorph…
Deformation of singularities via -algebras
Frank Schuhmacher
This is an addendum to the paper ``Deformation of -Algebras'' of the same author. We explain in which way the deformation theory of -algebras extends the deform…
Deformation of -Algebras
Frank Schuhmacher
In this paper, deformations of -algebras are defined in such a way that the bases of deformations are -algebras, as well. A universal and a semiuniversal deform…
Hochschild Cohomology for Complex Spaces and Noetherian Schemes
Frank Schuhmacher
The classical HKR-theorem gives an isomorphism of the n-th Hochschild cohomology of a smooth algebra and the n-th exterior power of its module of Kähler differentials. Here we gene…
