摘要: We introduce generalized excellent extension of ring R in [4]. If S is a generalized excellent extension of R, we prove that (1) wgldim S≤ wgldim R and glodim S≤ gldim R; (2) the relations between rings R and rings S. 

关键词: ( generalized) excellent extension, homological dimension, GV-Ring S 3 I-Ring
