Abstract

In this paper we prove that for any definable subset $X\subset \mathbb{R}^{n}$ in a polynomially bounded o-minimal structure, with $dim(X)
规则的投影和规则的覆盖最小的结构
在本文中,我们证明了对于多项式有界o-极小结构中的任何可定义子集$X\subet\mathbb{R}^{n}$,在$dim(X)<n$的情况下,存在一个有限的正则投影集(在Mostowski意义上)。在任何o-极小结构中,我们也给出了这个定理的一个弱版本,并且在非多项式有界的o-最小结构中给出了一个反例。作为一个应用,我们证明了在任何o-minimum结构中都存在Parusi’nski意义上的正则覆盖。
