摘要

Let K be a field and R = K[X_1, ···, x_n] be the polynomial ring in the variables X_1, ..., x_n. In this paper we prove that when u = {p_1, ??? p_m}, and B = {p'_1,..., p'_t} are two arbitrary sets of monomial prime ideals of R, then there exist monomial ideals I and J of R such that I ? J, Ass∞(I) = u U B, Ass_R(R/J) = B, and Ass_R(J/I)= uB, where Ass~∞ (I) is the stable set of associated prime ideals of I. Also we show that when p_1,...p_m, are nonzero monomial prime ideals of R generated by disjoint nonempty subsets of {x_1,...,x_n}, then there exists a square-free monomial ideal I such that Ass_R(R/I~k) = Ass~∞(I) = {p_1,...,p_m}for all k ≥1.

J,Ass∞(I)= u UB,Ass_R(R / J)= B,并且Ass_R(J / I)= u B,其中Ass〜∞(I)是I的关联素理想的稳定集合。我们还表明,当p_1,... p_m是{x_1,...,x_n}的不相交非空子集生成的R的非零单项素理想时,则存在无平方的单项理想I,如Ass_R(R / I〜k)= Ass〜∞(I)= {p_1,...,p_m},所有k≥1。
