### An EKR theorem for matchings in the complete graph

Download the slides (PDF)

The talk concerns the following higher-order analog of the Erdős-Ko-Rado theorem. For positive integers and with , let be the family of all matchings of size in the complete graph . For any edge ee in , the family , which consists of all sets in containing , is called the star centered at . We prove that if and is an intersecting family of matchings in , then , where is an edge in . We also prove that equality holds if and only if is a star. The main technique we use to prove the theorem is an analog of Katona’s elegant cycle method.
