43 p, 1.0 MB Categorical methods in graded ring theory / Del Río, Ángel (Universidad de Murcia. Departamento de Matemáticas)
Let G be a group, R a G-graded ring and X a right G-set . We study functors between categories of modules graded by G-sets, continuing the work of [M]. As an application we obtain generalizations of Cohen-Montgomery Duality Theorems by categorical methods. [...]

8 p, 205.3 KB Weak dimension of group-graded rings. / Del Río, Ángel (Universidad de Murcia. Departamento de Matemáticas)
We study the weak dimension of a group-graded ring using methods developed in [B1], [Q] and [R]. We prove that if R is a G-graded ring with G locally finite and the order of every subgroup of G is invertible in R, then the graded weak dimension of R is equal to the ungraded one.
