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., the graph composed of the vertices adjacent to v and all edges connecting vertices adjacent … See more 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, … See more 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.

WebAug 19, 2024 · A graph is said to be complete if it’s undirected, has no loops, and every pair of distinct nodes is connected with only one edge. Also, we can have an n-complete graph Kn depending on the number of vertices. Example of the first 5 complete graphs. We should also talk about the area of graph coloring. WebFeb 1, 2024 · If the edges between the nodes are undirected, the graph is called an undirected graph. If an edge is directed from one vertex (node) to another, a graph is called a directed graph. An directed edge is called an arc. Though graphs may look very theoretical, many practical problems can be represented by graphs.
