Localized hypergraph clique-weight conjecture

About 3 years old · traced to

Let H\mathcal{H} be a qq-uniform hypergraph with mm edges, let \K(H)\K(\mathcal{H}) denote its collection of cliques, and let t≥q>i≥1t\geq q>i\geq 1. For each I∈(V(H)i)I\in\binom{V(\mathcal{H})}{i}, define x(I)≥q−i−1x(I)\geq q-i-1 by

d(I)=(x(I)−iq−i),d(I)=\binom{x(I)-i}{q-i},

and for each T∈\K(H)T\in\K(\mathcal{H}) define

x(T)=max⁡{x(I):I∈(Ti)},s′(T)=1(x(T)−qt−q).x(T)=\max\{x(I):I\in\binom{T}{i}\},\qquad s'(T)=\frac{1}{\binom{x(T)-q}{t-q}}.

Localized hypergraph clique-weight conjecture. One has

∑T∈\K(H)s′(T)≤m(tq).\sum_{T\in\K(\mathcal{H})}s'(T)\leq\frac{m}{\binom{t}{q}}.

This is proposed as a localized version of a theorem of Kirsch and Radcliffe for hypergraphs, paralleling the paper's localized clique bounds. The supplied text gives no evidence that it has been proved or refuted.
