凸体的成对相交同素异形

Pairwise intersecting homothets of a convex body

Alexandr Polyanskii

摘要:

我们证明了$d$维中心对称凸体的最大成对相交正同素异形数至多为$3^{d+1}$,其中任何一个凸体的中心都不包含在其内部。同时,我们改进了Minkowski空间中$k$ -距离集的基数的上界.

英文摘要:

We show that the maximum number of pairwise intersecting positive homothets of a $d$-dimensional centrally symmetric convex body, none of which contains the center of another in its interior, is at most $3^{d+1}$. Also, we improve upper bounds for cardinalities of $k$-distance sets in Minkowski spaces.
