摘要
本文系统研究了半素PI-环本质(单边)理想及最大商环的有关性质,从PI-理论中著名的 Rowen非平凡相交定理出发,证明了半素 PI-环的本质(单边)理想包合一个本质两边理想(定理7,推论8),建立了半素PI-环本质(单边)理想与其中心本质理想的内在联系(定理 9,推论 10),并以此为基础,证明了半素 PI-环的最大商环是 PI的(定理 12),且半素 PI-环的每一正则元在其最大商环中是可逆的(定理 14).
We research some properties on the essential (one-sided) ideals and the maximal quotient rings of smiprime PI-rings. The main resu is proved in this paper are that if R is a semiprine PI-rings then every essential one-sided ideal of R contains an essential two-sided ideal of R (Th7, Cor8), the connection between essential one sided ideals of R and essential ideals of the center are indicated (Th9 Cor10), the maximal quotient ring of R is also PI (Th12), every regular element in R is invertible in maximal quotient ring (Th14).
