Center and Lie algebra of outer derivations for algebras of differential operators associated to hyperplane arrangements
Francisco Kordon, Thierry Lambre
We compute the center and the Lie algebra of outer derivations of a familiy of algebras of differential operators associated to hyperplane arrangements of the affine space A 3. The…
Lie-Rinehart and Hochschild cohomology for algebras of differential operators
Francisco Kordon, Thierry Lambre
Let be a Lie-Rinehart algebra such that is -projective and let be its universal enveloping algebra. In this paper we present a spectral sequence which converges…
The Hochschild cohomology of the enveloping algebra of a Lie-Rinehart pair
Francisco Kordon
Let be a Lie-Rinehart pair such that is -projective and let be its universal enveloping algebra. The purpose of this paper is to present a spectral sequence whic…
Hochschild cohomology of algebras of differential operators tangent to a central arrangement of lines
Francisco Kordon, Mariano Suárez-Álvarez
Given a central arrangement of lines in a -dimensional vector space over a field of characteristic zero, we study the algebra of diffe…
