摘要
Let I be an m-generated complete intersection monomial ideal in S=K vertical bar x(1).....x(n)vertical bar.We show thattheStanley depth of 1 is n-[m/2]. We also study the Upper-discrete structure for monomial ideals and prove that if I is a squarefree monomial ideal minimally generated by 3 elements, then the Stanley depth of I is n-1.
