V. Bergelson and N. Hindman proved that if xnn=1 is a sequence in (N,+), then for any IP set A there exists a sum subsystem ynn=1 of xnn=1 with the property that FS(ynn=1)FP(ynn=1)A. While extending this combined structure, we obtain that a stronger result holds for dynamical IP sets. But for any IP set, it is unknown.

动态IP 集合中的组合锯齿形结构

V. Bergelson 和 N. Hindman 证明,如果 Xnn=1 是一个序列 (N,+),那么对于任意 一世集合A存在一个求和子系统nn=1Xnn=1 与财产 F(nn=1)F(nn=1)一种. 在扩展这种组合结构的同时,我们获得了一个更强的结果适用于动态一世套。但对于任何一世 设置,未知。
