摘要
本文研究类似于VNL环的环的性质.称一个环R是几乎弱正则环(几乎π-正则环,几乎强π-正则环),如果对任意的a∈R,都有a或1-a是弱正则(π-正则,强π-正则)元.本文讨论这些新环的扩张,给出相关环之间的关系图,拓广了局部环和VNL环的研究.
In this paper,we investigate the properties of rings similar to the VNL rings.A ring R is said to be a almost weakly regular ring(almostπ-regular ring,almost stronglyπ-regular ring),provided that for any a∈R,either a or 1-a is weakly regular(π-regular,stronglyπ-regular).We discuss extensions of these new rings and give the relationship between relevant rings,which extend the study of local rings and VNL rings.
