Abstract: In this talk, I will discuss the proof of a degree version of the celebrated Erd\H os-Ko-Rado theorem: given $n>2k$, for every intersecting $k$-uniform hypergraph $H$ on $n$ vertices, there exists a vertex that lies on at most $\binom{n-2}{k-2}$ edges. A degree version of the Hilton-Milner theorem was also proved for sufficiently large $n$.

The talk is based on joint works with Peter Frankl, Jie Han and Yi Zhao.
