Algebras with non-periodic bounded modules

Abstract: We study weakly symmetric special biserial algebra of infinite representation type. We show that usually some socle deformation of such an algebra has non-periodic bounded modules. The exceptions are precisely the algebras whose Brauer graph is a tree with no multiple edges. If the algebra has a non-periodic bounded module then its Hochschild cohomology cannot satisfy the finite generation property (Fg) introduced in [10].

“…For instance, Condition (Fg) is invariant under various constructions, such as derived equivalence or singular equivalence of Morita type, see [16,22,19]. Condition (Fg) has been studied or shown to hold for large families of algebras in [24,26,25,5] among others, and support varieties have been studied for algebras that satisfy (Fg), see for instance [8,20].…”
