Rings Related to Stable Range Conditions

Mostly restricting himself to exchange rings with various kinds of conditions, Chen (mathematics, Hangzhou Normal U., China) treats the stable range condition as an element-wise condition on rings in its own right, but also shows its relationship to such topics as cancellation, of modules, comparability of modules, cleanness, K-theory, monoid theory, matrix theory, and topology. Most of the results are new, he says, and provide a general introduction to the theory of exchange rings with various conditions related to the stable range.
