In this talk, I will prove a degree version of the celebrated Erdos-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.
