A sheaf of Hochschild complexes on quasi-compact opens
Wendy Lowen
For a scheme X, we construct a sheaf C of complexes on X such that for every quasi-compact open subset U of X, C(U) is quasi-isomorphic to the Hochschild complex of the scheme U. S…

Obstruction theory for objects in abelian and derived categories
Wendy T. Lowen
In this paper we develop the obstruction theory for lifting complexes, up to quasi-isomorphism, to derived categories of flat nilpotent deformations of abelian categories. As a par…

Hochschild cohomology of abelian categories and ringed spaces
W. T. Lowen, M. Van den Bergh
This paper continues the development of the deformation theory of abelian categories introduced in a previous paper by the authors. We show first that the deformation theory of abe…
