On the linear intersection number of graphs

Autor: Klein, Hauke, Margraf, Marian

The celebrated Erdos, Faber and Lovasz conjecture may be stated as follows: Any linear hypergraph on v points has chromatic index at most v. We will introduce the linear intersection number of a graph, and use this number to give an alternative formu
