Hochschild and Ordinary Cohomology Rings of Small Categories
Let C be a small category and k a field. There are two interesting mathematical subjects: the category algebra kC and the classifying space |C| = BC. We study the ring homomorphism HH∗(kC) → H∗(|C|, k) and prove it is split surjective, using the factorization category of Quillen [16] and certain techniques from functor cohomology theory. This generalizes the well-known results for finite groups...
متن کاملTHE TANGENT COMPLEX AND HOCHSCHILD COHOMOLOGY OF En-RINGS
In this work, we study the deformation theory of En-rings and the En analogue of the tangent complex, or topological André-Quillen cohomology. We prove a generalization of a conjecture of Kontsevich, that there is a fiber sequence A[n − 1] → TA → HHEn (A)[n], relating the En-tangent complex and En-Hochschild cohomology of an En-ring A. We give two proofs: The first is direct, reducing the probl...
متن کاملProducts in Hochschild Cohomology and Grothendieck Rings of Group Crossed Products
We give a general construction of rings graded by the conjugacy classes of a finite group. Some examples of our construction are the Hochschild cohomology ring of a finite group algebra, the Grothendieck ring of the Drinfel’d double of a group, and the orbifold cohomology ring for a global quotient. We generalize the first two examples by deriving product formulas for the Hochschild cohomology ...
متن کاملInvariants of Group Rings
Since the foundation paper of M. Auslander and 0. Goldman [ 1 J, several authors have generalized constructions for studying group algebras over fields to separable algebras over commutative rings. Specifically, we have in mind the Schur index [20], the Schur exponent [18], the Schur group [S], and the uniform group [ 111. This paper gives additional properties of these constructions and studie...
متن کاملComputing group cohomology rings from the Lyndon-Hochschild-Serre spectral sequence
We describe a method for computing presentations of cohomology rings of small finite p-groups. The description differs from other accounts in the literature in two main respects. First, we suggest some techniques for improving the efficiency of the obvious linear algebra approach to computing projective resolutions over a group algebra. Second, we use an implementation of the multiplicative str...
