Abstract

Let II be a squarefree monomial ideal of a polynomial algebra over a field minimally generated by f1,...,frf_1,...,f_r of degree d1 d\geq 1, and a set EE of monomials of degree d+1\geq d+1. Let JIJ\subsetneq I be a squarefree monomial ideal generated in degree d+1\geq d+1. Suppose that all squarefree monomials of I(JE)I\setminus (J\cup E) of degree d+1d+1 are some least common multiples of fif_i. If JJ contains all least common multiples of two of (fi)(f_i) of degree d+2d+2 then \depthSI/Jd+1\depth_SI/J\leq d+1 and Stanley's Conjecture holds for I/JI/J.
