WebThe set of neighbors, called a (open) neighborhood NG ( v) for a vertex v in a graph G, consists of all vertices adjacent to v but not including v. When v is also included, it is called a closed neighborhood, denoted by NG [ v ]. When stated without any qualification, a neighborhood is assumed to be open.

Neighbourhoods are also used in the clustering coefficient of a graph, which is a measure of the average density of its neighbourhoods. Ver mais In graph theory, an adjacent vertex of a vertex v in a graph is a vertex that is connected to v by an edge. The neighbourhood of a vertex v in a graph G is the subgraph of G induced by all vertices adjacent to v, i.e., … Ver mais For a set A of vertices, the neighbourhood of A is the union of the neighbourhoods of the vertices, and so it is the set of all vertices adjacent to at least one member of A. Ver mais If all vertices in G have neighbourhoods that are isomorphic to the same graph H, G is said to be locally H, and if all vertices in G have neighbourhoods that belong to some graph family F, G is said to be locally F (Hell 1978, Sedláček 1983).
