Webgraph theory, branch of mathematics concerned with networks of points connected by lines. The subject of graph theory had its beginnings in recreational math problems (see number game), but it has grown into a … WebTheorem: In any graph with at least two nodes, there are at least two nodes of the same degree. Proof 1: Let G be a graph with n ≥ 2 nodes. There are n possible choices for the degrees of nodes in G, namely, 0, 1, 2, …, and n – 1. We claim that G cannot simultaneously have a node u of degree 0 and a node v of degree n – 1: if there were ...

A graph G = ( V, E) that is not simple can be represented by using multisets: a loop is a multiset { v, v } = { 2 ⋅ v } and multiple edges are represented by making E a multiset. The condensation of a multigraph may be formed by interpreting the multiset E as a set. A general graph that is not connected, has ...
