Containers for hypergraphs
WebJul 28, 2024 · 1.1 Triangle-Free Subgraphs of Hypergraphs. In this paper, we consider a generalization of the problem of determining {\mathrm {ex}} (G,F) when F is a triangle to uniform hypergraphs. We write r - graph instead of r -uniform hypergraph. If G and F are r -graphs, then {\mathrm {ex}} (G,F) denotes the maximum number of edges in an F -free ... Webour hypergraphs typically have infinitely many vertices. Similar considerations in a di˛erent infinitary setting have previously led the current authors together with Henry Towsner [Ber+18] to develop a nonalgorithmic proof of the containers theorem for finite hypergraphs. Unfortunately, the argument in

WebThis improves upon an earlier result of Hàn, Person, and Schacht for the range k / 2 < l ≤ k − 1. In many cases, our result gives a tight bound on δ l ( H) for near perfect matchings (e.g., when l ≥ 2 k / 3, n ≡ r ( mod k), 0 ≤ r < k, and r + l ≥ k, we can take m = ⌈ n / k ⌉ − 2 ). When k = 3, using an absorbing lemma of ... WebOct 21, 2024 · We prove a new, efficient version of the hypergraph container theorems that is suited for hypergraphs with large uniformities.
