环的efpPD(R)维数

F. P. P. DIMENSION OF RINGS

较一般地讨论efpPD(R)有限的环的性质,推广了丁南庆研究efpPD(R)的一些结果。而H.Bass研究的两个结果属讨论结果的推论。

This paper studies the properties of finite rings R with efpPD( R) more generally, and extendes some results of Ding Nan-Qing's studies on efpPD(R). Two results by H. Bass are the corollaries of the results of this paper.
