Finitistic dimensions of rings - cuni.cz
Webrings are precisely those rings where all modules have Gorenstein flat-cotorsion dimension at most zero. In the second, we show that Quasi-Frobenius rings are those rings where all modules are Gorenstein flat-cotorsion. Further, we show in Theorems 4.5 and 4.9 that under assumptions of finite finitistic dimensions, rings of finite Gorenstein ... WebFeb 28, 2024 · An extension of algebras is a homomorphism of algebras preserving identities. We use extensions of algebras to study the finitistic dimension conjecture over Artin algebras. Let be an extension of Artin algebras. We denote by the relative finitistic dimension of , which is defined to be the supremum of relative projective dimensions of … WebJun 10, 2016 · The global dimension and finitistic dimension of A σ α G are classified: global dimension of A σ α G is either infinity or equal to that of A, and finitistic dimension of A σ α G coincides with that of A. A criterion for skew group rings to have finite global dimensions is deduced. helicopter jokes
