On the stability of graded rings
If \(R\) is a ring graded by the integers, which is noetherian and left graded regular, such that every finitely generated graded projective \(R\)- module is graded stably free, then it is shown that the corresponding ungraded property holds. Some applications to Rees rings of Zariskian filtered rings are given.
