Support varieties - an ideal approach
Aslak Bakke Buan, Henning Krause, Øyvind Solberg
We define support varieties in an axiomatic setting using the prime spectrum of a lattice of ideals. A key observation is the functoriality of the spectrum and that this functor ad…
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…
