On properties of graded rings and graded modules

open access: yesProyecciones (Antofagasta), 2022
Let R be a G-graded ring. In this article, we introduce two new concepts on graded rings, namely, weakly graded rings and invertible graded rings, and we discuss the relations between these concepts and several properties of graded rings. Also, we study the concept of weakly crossed products and study some properties defined on weakly crossed product ...

Grade schemes and grade functions [PDF]

open access: yesTransactions of the American Mathematical Society, 1985
Let R be a Noetherian ring. An R-sequence \(x_ 1,...,x_ n\) is built by always choosing \(x_ i\) to be not in the union of the primes in Ass R/(x\({}_ 1,...,x_{i-1})R\). In the terminology of this paper, \(A(I)=Ass R/I\) is a grade scheme and its associated grade function is \(f(I)=the\) (classical) grade of I. If instead, we take \(A(I)=\{P| P\quad is\
