Abstract
Let r(k) denote the maximum number of edges in a k-uniform intersecting family with covering number k. ErdÅs and Lovász proved that âk!(eâ1)ââ¤r(k)â¤kk. Frankl, Ota, and Tokushige improved the lower bound to r(k)â¥(k/2)kâ1, and Tuza improved the upper bound to r(k)â¤(1âeâ1+o(1))kk. We establish that r(k)â¤(1+o(1))kkâ1.
