Support varieties over skew complete intersections via derived braided Hochschild cohomology

نویسندگان

چکیده

In this article we investigate homological aspects of a skew complete intersection R, i.e. polynomial ring modulo an ideal generated by sequence regular normal elements. We compute the derived braided Hochschild cohomology R relative to and show its action on ExtR(M,N) is noetherian for finitely R-modules M N respecting braiding R. When parameters defining are roots unity use define support theory. setting applications include proof Generalized Auslander-Reiten Conjecture that possesses symmetric complexity.

On Support Varieties for Modules over Complete Intersections

Let (A, m, k) be a complete intersection of codimension c, and k̃ the algebraic closure of k. We show that every homogeneous algebraic subset of k̃c is the cohomological support variety of an A-module, and that the projective variety of a complete indecomposable maximal Cohen-Macaulay A-module is connected.

Hochschild Cohomology and Support Varieties for Tame Hecke Algebras

We give a basis for the Hochschild cohomology ring of tame Hecke algebras. We then show that the Hochschild cohomology ring modulo nilpotence is a finitely generated algebra of Krull dimension 2, and describe the support varieties of modules for these algebras.

Which Schubert varieties are local complete intersections?

We characterize by pattern avoidance the Schubert varieties for GLn which are local complete intersections (lci). For those Schubert varieties which are local complete intersections, we give an explicit minimal set of equations cutting out their neighborhoods at the identity. Although the statement of our characterization only requires ordinary pattern avoidance, showing that the Schubert varie...
