摘要
利用Pn-内射模和Pn-平坦模引入并研究了PnP环,得到了Pn-平坦预包络存在性和右PnP环的性质的刻画,推广了预包络存在性和PP环的相关研究.
Pn-injective modules and Pn-flat modules are introduced to investigate PnP rings,the existences of Pn-flat preenvelope are obtained and right PnP rings are characterized,which generalized those results of the existence of preenvelopes and PP rings.
