欧几里得空间中的盒、扩张盒和正上密度集

Boxes, extended boxes, and sets of positive upper density in the Euclidean space

Polona Durcik, Vjekoslav Kovač

摘要:

我们证明了在足够大的维度上具有正的上Banach密度的集合包含三个特定的高维模式的所有足够大的扩张的全等副本。这些模式是:固定的$n$维矩形框的$2^n$顶点,相同的顶点用完成三项等差数列的$n$点扩展,并且相同的顶点用完成三点角的$n$点扩展。我们的结果提供了共同的推广几个欧几里德密度定理从文献中。

英文摘要:

We prove that sets with positive upper Banach density in sufficiently large dimensions contain congruent copies of all sufficiently large dilates of three specific higher-dimensional patterns. These patterns are: $2^n$ vertices of a fixed $n$-dimensional rectangular box, the same vertices extended with $n$ points completing three-term arithmetic progressions, and the same vertices extended with $n$ points completing three-point corners. Our results provide common generalizations of several Euclidean density theorems from the literature.
