Sometimes the boundary and the boundary approximately equate, sometimes the boundary contains the ideal condition, but the boundary and the ideal condition not are a chapter of matter.

境與境界有時(shí)大致等同，境有時(shí)包含意境在內(nèi)久久va中文字幕影视，但境界與意境并不就是一回事情。

The first chapter, main instead " duo-ring " condition of " every maximal left ideal is GW-ideal " condition,study strongly regularities of GP-V-ring on this condition.lt is shown that (1) R is strongly regular iff R is left GP-V-ring whose maximal left ideals are GW-ideal.(2)R is strongly regular iff R is left GP-V-ring whose maximal right ideals are GW-ideal. The second chapter, generalize some results of GP-V-ring to GP-V-ring, discuss regularity of GP-V-ring.It is shown that (1) R is left self-injective regular with non-zero socle iff R is left GP-V -ring with Soc = Soc and R contains an injective maximal left ideal.(2)R is regular ring and every maximal essential left ideal is ideal iff R is left GP-injective left GP-V -ring and every maximal essential left ideal is ideal.

第一章主要將"duo-環(huán)"條件替換成"每一極大左理想是GW-理想"條件色色香蕉色色色，研究在此條件下毛片a视频，GP-V-環(huán)的強(qiáng)正則性，證明了：(1)R是強(qiáng)正則環(huán)當(dāng)且僅當(dāng)R是左GP-V-環(huán)且R的每一極大左理想是廣義弱理想欧美色爱区；(2)R是強(qiáng)正則環(huán)當(dāng)且僅當(dāng)R是左GP-V-環(huán)且R的每一極大右理想是廣義弱理想国产免费污网站在线观看，第二章，主要將GP-V-環(huán)上一些結(jié)果推廣到GP-V′-環(huán)上天堂AV在线播放最新版，討論GP-V′-環(huán)的正則性精品射射射福利一区，證明了：(1)R是左自內(nèi)射正則環(huán)且Soc≠0當(dāng)且僅當(dāng)R是包含內(nèi)射極大左理想的GP-V′-環(huán)，且Soc=Soc免费黄色在线啊～啊～；(2)R是正則環(huán)且每一極大本質(zhì)左理想是理想當(dāng)且僅當(dāng)R是左GP-內(nèi)射的左GP-V′-環(huán)且每一極大本質(zhì)左理想是理想亚洲国产一区二区三区青草影视。
