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…

K-theory of the norm functor
Max Karoubi, Thierry Lambre
The K-theory of a functor may be viewed as a relative version of the K-theory of a ring. In the case of a Galois extension of a number field F/L with rings of integers A/B respecti…
