英文摘要: |
A ring R is called left Gp-injective if for any a∈R, there exists a positive integer n such that any left R-homomorphism of Ran into R extends to one of R into R. In this paper, we prove that the centre of semiprime (left nonsingular) left GP- injective ring is regular ring, and improve some propositions in [3]. |
