چکیده
We investigate the problem when tensor functor by a bimodule yields singular equivalence. It turns out that this is equivalent to one Hom given same induces triangle equivalence between homotopy categories of acyclic complexes injective modules. give conditions on appears in pair bimodules, defines with level. construct an explicit combinatorial manner, which quadratic monomial algebra and its associated radical square zero. Under certain include Gorenstein cases, does appear bimodules defining

Morita Equivalences Induced by Bimodules over Hopf-galois Extensions
Let H be a Hopf algebra, and A, B be H-Galois extensions. We investigate the category AM H B of relative Hopf bimodules, and the Morita equivalences between A and B induced by them. Introduction This paper is a contribution to the representation theory of Hopf-Galois extensions, as originated by Schneider in [15]. More specifically, we consider the following questions. Let H be a Hopf algebra, ...
متن کاملA-H-bimodules and equivalences
In [6, Theorem 2.2] Doi gave a Hopf-algebraic proof of a generalization of Oberst’s theorem on affine quotients of affine schemes. He considered a commutative Hopf algebra H over a field, coacting on a commutative H-comodule algebra A. If AcoH denotes the subalgebra of coinvariant elements of A and β : A ⊗AcoH A −→ A ⊗H the canonical map, he proved that the following are equivalent: (a) AcoH ⊂ ...

Let K be a field of characteristic 0 containing all roots of unity. We classified all the Hopf structures on monomial K-coalgebras, or, in dual version, on monomial K-algebras. 2004 Elsevier Inc. All rights reserved.
متن کاملDerived equivalences and Gorenstein algebras
In this note, we introduce the notion of Gorenstein algebras. Let R be a commutative Gorenstein ring and A a noetherian R-algebra. We call A a Gorenstein R-algebra if A has Gorenstein dimension zero as an R-module (see [2]), add(D(AA)) = PA, where D = HomR(−, R), and Ap is projective as an Rpmodule for all p ∈ Spec R with dim Rp < dim R. Note that if dim R = ∞ then a Gorenstein R-algebra A is p...
متن کاملBimodules associated to vertex operator algebras
Let V be a vertex operator algebra and m,n ≥ 0. We construct an An(V )Am(V )-bimodule An,m(V ) which determines the action of V from the level m subspace to level n subspace of an admissible V -module. We show how to use An,m(V ) to construct naturally admissible V -modules from Am(V )-modules. We also determine the structure of An,m(V ) when V is rational. 2000MSC:17B69
