设(R, m)是一个局部环。我们研究了当存在一个正整数h,使得对于所有素数理想P≥1,P (hn)的符号幂P (hn)都包含在pn中,且对所有n≥1。我们证明当R是一个简化孤立奇点时,这样的h存在,使得R要么包含一个正特征域,并且R是F有限的,要么R本质上是有限型的,在特征为零的域上。
Let (R, m) be a local ring. We study the question of when there exists a positive integer h such that for all prime ideals P ⊆ R, the symbolic power P (hn) is contained in P n, for all n ≥ 1. We show that such an h exists when R is a reduced isolated singularity such that R either contains a field of positive characteristic and R is F -finite or R is essentially of finite type over a field of characteristic zero.
