近向日葵和焦点科
Near-sunflowers and focal families
摘要:
我们提出了一些问题和结果的变种向日葵在家庭的集合。特别是,我们提高了第一作者,Körner和蒙蒂的最大数量的二进制向量的长度$n$,使每四个被分裂成两对的一些坐标的上限。我们还提出了一个较弱的版本的Erdens-Rado向日葵猜想。
英文摘要:
We present some problems and results about variants of sunflowers in families of sets. In particular, we improve an upper bound of the first author, Körner and Monti on the maximum number of binary vectors of length $n$ so that every four of them are split into two pairs by some coordinate. We also propose a weaker version of the Erdős-Rado sunflower conjecture.
