Abstract

In this short note, we provide the necessary and sufficient condition for an infinite collection of axis-parallel boxes in Rd to be pierceable by finitely many axis-parallel k-flats, where 0k<d. We also consider colorful generalizations of the above result and establish their feasibility. The problem considered in this paper is an infinite variant of the Hadwiger-Debrunner (p,q)-problem.

具有有限多条轴平行线和平面的刺盒
在这篇短文中,我们提供了一个必要条件和充分条件,即 Rd 中轴对称的无穷盒集合可被有限多个轴对称的 k 平面(其中 0≤k<d 时)穿透。我们还考虑了上述结果的丰富多彩的一般化,并确定了它们的可行性。本文考虑的问题是哈德维格-德布鲁纳(p,q)问题的无限变体。

期刊介绍: Discrete Mathematics provides a common forum for significant research in many areas of discrete mathematics and combinatorics. Among the fields covered by Discrete Mathematics are graph and hypergraph theory, enumeration, coding theory, block designs, the combinatorics of partially ordered sets, extremal set theory, matroid theory, algebraic combinatorics, discrete geometry, matrices, and discrete probability theory. Items in the journal include research articles (Contributions or Notes, depending on length) and survey/expository articles (Perspectives). Efforts are made to process the submission of Notes (short articles) quickly. The Perspectives section features expository articles accessible to a broad audience that cast new light or present unifying points of view on well-known or insufficiently-known topics.
