An Averaging Process for Unipotent Group Actions
Amnon Yekutieli
We present an averaging process for sections of a torsor under a unipotent group. This process allows one to integrate local sections of such a torsor into a global simplicial sect…
Mixed Resolutions and Simplicial Sections
Amnon Yekutieli
We introduce the notions of mixed resolutions and simplicial sections, and prove a theorem relating them. This result is used (in another paper) to study deformation quantization i…
Continuous and Twisted L_infinity Morphisms
Amnon Yekutieli
The purpose of this paper is to develop a suitable notion of continuous L_infinity morphism between DG Lie algebras, and to study twists of such morphisms.
Homological Transcendence Degree
Amnon Yekutieli, James J. Zhang
Let D be a division algebra over a base field k. The homological transcendence degree of D, denoted by Htr D, is defined to be the injective dimension of the enveloping algebra of…
On the Structure of Behaviors
Amnon Yekutieli
A behavior is a closed shift invariant subspace of the space of sequences with entries in a field k. We work out an explicit duality for k-modules. This duality is then used to der…
Deformation Quantization in Algebraic Geometry
Amnon Yekutieli
We study deformation quantizations of the structure sheaf O_X of a smooth algebraic variety X in characteristic 0. Our main result is that when X is D-affine, any formal Poisson st…
