TLDR
In this article, the celebrated Erdos, Faber and Lovasz Conjecture may be expressed as follows: any linear hypergraph on ν points has chromatic index at most ν, where ν denotes the linear intersection number and χ denotes the chromatic number of the graph.
Abstract
The celebrated Erdos, Faber and Lovasz Conjecture may be stated as follows: Any linear hypergraph on ν points has chromatic index at most ν We show that the conjecture is equivalent to the following assumption: For any graph \(\chi(G) \leq \nu(G)\), where ν(G) denotes the linear intersection number and χ(G) denotes the chromatic number of G As we will see \(\chi(G) + \chi(\bar{G}) \leq \nu(G)+ \nu(\overline{G})\) for any graph G = (V, E), where \((\overline{G})\) denotes the complement of G Hence, at least G or \(\overline{G}\) fulfills the conjecture

The Erdős–Faber–Lovász conjecture is true for n ≤ 12

TL;DR: Hindman proved the conjecture that if a hypergraph has n edges, each of size n, and every pair of edges intersect in at most one vertex, then its vertex chromatic number is equal to n.

On hyperedge coloring of weakly trianguled hypergraphs and well ordered hypergraphs

TL;DR: This article proves the assertion that every loopless linear hypergraph H on n vertices can be n -edge-colored, or equivalently q ( H ) ≤ n, where q (H ) is the chromatic index of H, i.e. the smallest number of colors such that intersecting hyperedges of H are colored with distinct colors.

Coloring nearly-disjoint hypergraphs with n + o(n) colors

TL;DR: This is an approximate version of the well-known conjecture of Erdős, Faber, and Lovasz stating that the chromatic index of a nearly-disjoint hypergraph on n vertices is at most n + o ( n ).

On some hypergraph problems of paul erdős and the asymptotics of matchings, covers and colorings

TL;DR: This article summarizes progress on several old hypergraph problems of Paul Erdős and a few questions to which they led and some indication (if any were needed) that Erd� Hungarian questions were the “right” ones.
