摘要 主要证明了右P-V′、右AP-内射环是左非奇异的,并且研究了非奇异的AP-内射环的正则性.最后,给出一个例子说明AP-内射环和P-V′-环均不具有左、右对称性. In this paper, discuss the regularity of right AP- injective ring we mainly prove that right P-V' and right AP- injective rings are left nonsingular and right nonsingular AP- injective rings. In addition, we give an example of left P-V', but neither right P-V'- ring nor left AP- injective ring.
