Resolutions over Koszul algebras

E. L. Green, G. Hartman, E. N. Marcos +1

In this paper we show that if $Λ = ⨿_{i \geq 0} Λ_{i}$ is a Koszul algebra with $Λ_{0}$ isomorphic to a product of copies of a field, then the minimal projective resolution of $Λ_{0}$ 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 $n$ -th Hochschild cohomology group of a finite dimensional algebra $Γ$ over a field vanishes for all sufficiently large $n$ , 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 $Λ$ over a field $K$ we show that the Hochschild cohomology ring of $Λ$ modulo the ideal generated by homogeneous nilpotent elements is a…
