本文给出了n 0(I)的一个界,从这个界出发,无平方项理想I的符号幂商环的深度函数深度R/I(n)是稳定的.在非混合余维二的情况下,我们证明深度R/I(n)是n的非增函数,并使用此属性提供n 0(I)的精确界。
We give a bound for n 0 (I) from which the depth function depth R/I (n) of the quotient ring by symbolic powers of a squarefree monomial ideal I stabilizes. In the unmixed codimension two case we show that depth R/I (n) is a non-increasing function of n and use this property to provide a sharp bound for n 0 (I).
