### Lagrangians of hypergraphs: The Frankl-Füredi conjecture holds almost everywhere

Abstract:

Frankl and Füredi conjectured in 1989 that the maximum Lagrangian of all r-uniform hypergraphs of fixed size m is realised by the initial segment of the colexicographic order. In particular, in the principal case m=(tr) that every H⊆N(r)of size (tr) satisfies max⁡{∑A∈H∏i∈Ayi:y1,y2,…≥0;∑i∈Nyi=1}≤[Formula presented](tr). We prove the above statement for all r≥4 and large values of t (the case r = 3 was settled by Talbot in 2002). More generally, we show for any r≥4 that the Frankl-Füredi conjec...
