关于Unit J-clean环OACSTPCD
On Unit J-clean Rings
一个元素叫做右单位 J‐clean(左单位 J‐clean)如果在 R中存在一个单位u ,使得 au(ua)是 J‐clean的。一个环R叫做右单位J‐clean(左单位 J‐clean)环当且仅当环中的每个元素都是右单位 J‐clean(左单位 J‐clean)的。文章得到了以下几个结论:每个 J‐clean环是 unit J‐clean环,每个unit J‐clean环是 unit clean环,每个2‐good环是unit clean环,但…查看全部>>
An element a∈ R right (left) unit J‐clean if there is a unit u∈ R such that au (ua) is J‐clean .A ring R is called right (left) unit J‐clean if each element is right (left) unit J‐clean .In this paper ,we get the re‐sults that every J‐clean ring is unit J‐clean ,every unit J‐clean is unit clean and every 2‐good ring is unit clean but the converse of all the three conclusions are not true .Further ,we prove that for a unit J‐clean ring R is 2‐good if and only…查看全部>>
