设R是交换环,引入Lucas模与模的Lucas包络的概念,证明理想I的Lucas包络Q_(0)(I)≠Q_(0)(R)当且仅当I是R的非半正则理想;也引入Q_(0)-Noether环的概念,并证明R是Q_(0)-Noether环当且仅当多项式环R[x_(1),x_(2),…,x_(n)]是Q_(0)-Noether环.

Zero-dimensional valuation rings are one kind of non-Noetherian rings.This paper investigates properties of zero-dimensional valuation rings and prove that a finitely generated ideal over such a ring has a Grobner basis.The authors present an algorithm for computing a Gr?bner basis of a finitely generated ideal over it.Furthermore,an interesting example is also provided to explain the algorithm. 展开更多
