On neighborhood-Helly graphs
A family F of subsets of some set is intersecting when sets of F pairwise intersect. The family F is Helly when every intersecting subfamily of it contains a common element. In this paper we examine the families of vertex neighborhoods of a graph, with the aim of determining whether or not they are...
