Resolving Adenwalla's conjecture related to a question of ErdÅs and Graham about covering systems

Zhengkun Jia, Huixi Li, Yushuo Liu

ErdÅs and Graham posed the question of whether there exists an integer $n$ such that the divisors of $n$ greater than $1$ form a distinct covering system with pairwise coprime mod…

Non-uniform Cross-intersecting Families

Zhen Jia, Qing Xiang, Jimeng Xiao +1

Let $m \geq 2$ , $n$ be positive integers, and $R_{i} = {k_{i, 1} > k_{i, 2} > \dots > k_{i, t_{i}}}$ be subsets of $[n]$ for $i = 1, 2, \dots, m$ . The families $\mathcal{F}_1\subseteq \binom{[n]…
