The Gabriel-roiter Measure for Radical-square Zero Algebras
Let Λ be a radical-square zero algebra over an algebraically closed field k with radical r and Γ = Λ/r 0 r Λ/r ! be the associated hereditary algebra. There is a well-known functor F : modΛ→modΓ which induces a stable equivalence. We show that the functor F keeps Gabriel-Roiter measures and Gabriel-Roiter factors. Thus one may study the Gabriel-Roiter measure for Λ using F and known facts for h...
متن کاملAlgebras with Radical Square Zero Are Either Self-injective or Cm-free
An artin algebra is called CM-free provided that all its finitely generated Gorenstein projective modules are projective. We show that a connected artin algebra with radical square zero is either self-injective or CM-free. As a consequence, we prove that a connected artin algebra with radical square zero is Gorenstein if and only if its valued quiver is either an oriented cycle with the trivial...
متن کاملThe Lie Module Structure on the Hochschild Cohomology Groups of Monomial Algebras with Radical Square Zero
We study the Lie module structure given by the Gerstenhaber bracket on the Hochschild cohomology groups of a monomial algebra with radical square zero. The description of such Lie module structure will be given in terms of the combinatorics of the quiver. The Lie module structure will be related to the classification of finite dimensional modules over simple Lie algebras when the quiver is give...
متن کاملRadical Cube Zero Weakly Symmetric Algebras and Support Varieties
One of our main results is a classification all the weakly symmetric radical cube zero finite dimensional algebras over an algebraically closed field having a theory of support via the Hochschild cohomology ring satisfying Dade’s Lemma. Along the way we give a characterization of when a finite dimensional Koszul algebra has such a theory of support in terms of the graded centre of the Koszul dual.
متن کاملRadical Cube Zero Selfinjective Algebras of Finite Complexity
One of our main results is a classification all the possible quivers of selfinjective radical cube zero finite dimensional algebras over an algebraically closed field having finite complexity. In the paper [5] we classified all weakly symmetric algebras with support varieties via Hochschild cohomology satisfying Dade’s Lemma. For a finite dimensional algebra to have such a theory of support var...
