摘要
证明了置换环上n-稳定秩条件关于Morita Context是遗传的;进一步把该结果推广到了强可分环,从而提供了新的具有模消去的置换环。
It is shown that n-stable range conditions over exchange rings can be inherited by general contexts. By introducing strongly separative modules, the authors extend this result to strongly separative rings. These provide new classes of exchange rings with cancellations of modules.
