Improved bounds on the Ramsey number of fans

Guantao Chen, Xiaowei Yu, Yi Zhao

For a given graph $H$ , the Ramsey number $r (H)$ is the minimum $N$ such that any 2-edge-coloring of the complete graph $K_{N}$ yields a monochromatic copy of $H$ . Given a positive in…

Minimum degree thresholds for Hamilton $(k /2)$ -cycles in $k$ -uniform hypergraphs

Hiep Han, Jie Han, Yi Zhao

For any even integer $k \geq 6$ , integer $d$ such that $k /2 \leq d \leq k - 1$ , and sufficiently large $n \in (k /2) N$ , we find a tight minimum $d$ -degree condition that guarantees t…
