Title: A hypergraph analog of Dirac’s Theorem for 2-connected graphs

Abstract: Every graph with minimum degree $k \geq 2$ contains a cycle of length at least $k+1.$ Dirac proved that if the graph is also 2-connected then in fact we can find a cycle of length at least $min\{2k, n\}$. We prove a hypergraph version of this theorem: a minimum degree condition that forces the existence of long Berge cycles in 2-connected, uniform hypergraphs. This is joint work with Alexandr Kostochka and Grace McCourt.
