Abstract
We use an algebraic method to prove a degree version of the celebrated Erd\H os-Ko-Rado theorem: given , every intersecting -uniform hypergraph on vertices contains a vertex that lies on at most edges. This result can be viewed as a special case of the degree version of a well-known conjecture of Erd\H{o}s on hypergraph matchings. Improving the work of Bollob\'as, Daykin, and Erd\H os from 1976, we show that given integers with , every -uniform hypergraph on vertices with minimum vertex degree greater than contains disjoint edges.
