Wheels in planar graphs and Hajós graphs

Qiqin Xie, Shijie Xie, Xingxing Yu +1

It was conjectured by Hajós that graphs containing no $K_{5}$ -subdivision are 4-colorable. Previous results show that any possible minimum counterexample to Hajós' conjecture, called…

Near perfect matchings in uniform hypergraphs

Hongliang Lu, Xingxing Yu, Xiaofan Yuan

In this paper, we study degree conditions for the existence of large matchings in uniform hypergraphs. We prove that for integers $k, l, n$ with $k \geq 3$ , $k /2 < l < k$ , and $n$ large, i…
