On support varieties and tensor products for finite dimensional algebras
Petter Andreas Bergh, Mads Hustad Sandøy, Øyvind Solberg
It has been asked whether there is a version of the tensor product property for support varieties over finite dimensional algebras defined in terms of Hochschild cohomology. We sho…
Resolutions over Koszul algebras
E. L. Green, G. Hartman, E. N. Marcos +1
In this paper we show that if is a Koszul algebra with isomorphic to a product of copies of a field, then the minimal projective resolution of a…
Finite Hochschild cohomology without finite global dimension
R. -O. Buchweitz, E. L. Green, D. Madsen +1
Dieter Happel asked the following question: If the -th Hochschild cohomology group of a finite dimensional algebra over a field vanishes for all sufficiently large , is t…
The Hochschild cohomology ring modulo nilpotence of a monomial algebra
E. L. Green, N. Snashall, Ø. Solberg
For a finite dimensional monomial algebra over a field we show that the Hochschild cohomology ring of modulo the ideal generated by homogeneous nilpotent elements is a…
