中文摘要 AI 辅助

我们证明了带容差的Tverberg定理的新界。我们证明$N = rt+\Theta_{d,r}(t^{1/2-1/(2d)})$,其中$N$是最小的数,使得$\mathbb{R}^d$中任意$N$个点的集合都有一个划分为$r$部分,使得即使移除任意$t$个点,各部分的凸包仍然相交。我们将带容差的Tverberg定理推广到$\mathbb{R}^d$中的超平面族,并证明对于$\mathbb{R}^d$中任意$rt + O_{d,r}(t^{1/2-1/(2d)}\sqrt{\log (t+1)})$个超平面的集合,存在一个将它们划分为$r$部分的划分,使得即使移除任意$t$个超平面,各部分的回归凸包仍然相交。我们的界是通过建立Tverberg型结果与差异理论之间的联系而得出的。

英文摘要

We prove new bounds for Tverberg's theorem with tolerance. We show that $N = rt+Θ_{d,r}(t^{1/2-1/(2d)})$, where $N$ is the smallest number such that any set of $N$ points in $\mathbb{R}^d$ has a partition into $r$ parts such that the convex hulls of the parts intersect even if we remove any $t$ of the points. We extend Tverberg's theorem with tolerance to families of hyperplanes in $\mathbb{R}^d$, and show that for any set of $rt + O_{d,r}(t^{1/2-1/(2d)}\sqrt{\log (t+1)})$ hyperplanes in $\mathbb{R}^d$ there exists a partition of them into $r$ parts such that the regression hulls of the parts intersect even if any $t$ hyperplanes are removed. Our bounds follow from establishing a connection between Tverberg-type results and discrepancy theory.
