Calabi-Yau coalgebras
J. -W. He, B. Torrecillas, F. Van Oystaeyen +1
We provide a construction of minimal injective resolutions of simple comodules of path coalgebras of quivers with relations. Dual to Calabi-Yau condition of algebras, we introduce…
Dualities of artinian coalgebras with applications to noetherian complete algebras
J. -W. He, B. Torrecillas, F. Van Oystaeyen +1
A duality theorem of the bounded derived category of quasi-finite comodules over an artinian coalgebra is established. Let be a noetherian complete basic semiperfect algebra ov…
Approximate and pseudo-amenability of various classes of Banach algebras
Y. Choi, F. Ghahramani, Y. Zhang
We continue the investigation of notions of approximate amenability that were introduced in work of the second and third authors. It is shown that every boundedly approximately con…
The equivariant Brauer group of a group
S. Caenepeel, F. Van Oystaeyen, Y. H. Zhang
We consider the Brauer group of a group (finite or infinite) over a commutative ring with identity. A split exact sequence $$1\longrightarrow {\rm Br}'(k)\…
