The Structure of Hypergraphs without long Berge cycles

Combinatorics 2019-07-12 v2

Abstract

We study the structure of rr-uniform hypergraphs containing no Berge cycles of length at least kk for krk \leq r, and determine that such hypergraphs have some special substructure. In particular we determine the extremal number of such hypergraphs, giving an affirmative answer to the conjectured value when k=rk=r and giving a a simple solution to a recent result of Kostochka-Luo when k<rk < r.
