Degree versions of the Erdos-Ko-Rado Theorem and Erdos hypergraph matching conjecture

Hao Huang, Yi Zhao

We use an algebraic method to prove a degree version of the celebrated Erd\H os-Ko-Rado theorem: given $n > 2 k$ , every intersecting $k$ -uniform hypergraph $H$ on $n$ vertices contain…

Asymptotics of Ramsey numbers of double stars

Sergey Norin, Yue Ru Sun, Yi Zhao

A double star $S (n, m)$ is the graph obtained by joining the center of a star with $n$ leaves to a center of a star with $m$ leaves by an edge. Let $r (S (n, m))$ denote the Ramsey num…
