So if we proof that two adjacent vertices have the same degree, all vertices have the same degree. 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 … See more • Markov blanket • Moore neighbourhood • Von Neumann neighbourhood • Second neighborhood problem • Vertex figure, a related concept in polyhedra See more part of the ear crossword clue

"Webgraph. A molecular graph is a collection of points representing the atoms in the molecule and set of lines representing the covalent bonds. These points are named vertices and the lines are named edges in graph theory language. In mathematical terms a graph is represented as G =(V,E) where V is the set of vertices and E is the set of edges. " - Graph theory common neighbourhood
