| Abstract: | It is shown that a ring R is a GM-ring if and only if there exists a complete orthogonal set { e
1,...,e
n
} of idempotents such that all e
i
Re
i
are GM-rings. We also investigate GM-rings for Morita contexts, module extensions and power series rings.This work was supported by the Natural Science Foundation of Zhejiang Province. |
