Abstract

As is well known, a simple nondirected graph is a mathematical object modeling the existence of a certain relation between pairs of elements of a given set. It is therefore not surprising that, at the beginning, many of the results concerning graphs made reference to relationships between a group of people. In this expository article, we comment on four results of this kind, as representatives or as a source of inspiration for various general theories on graphs and their applications. In some cases, such as Halls marriage theorem, we also describe its relation to other topics of graph theory, as network connectivity.
