It is an Eulerian circuit if it starts and ends at the same vertex. _\square . The informal proof in the previous section, translated into the language of graph theory, shows immediately that: If a graph admits an Eulerian path, then there are ...
In graph theory, a branch of mathematics, the handshaking lemma is the statement that, in every finite undirected graph, the number of vertices that touch an odd number of edges is even. For example, if there is a party of people who shake hands, the number of people who shake an odd number of other people's hands is even. The handshaking lemma is a consequence of the degree sum … WebTheorem:Every simple graph G is always max degree( G )+1 colorable. I Proof is by induction on the number of vertices n . I Let P (n ) be the predicate\A simple graph G with n vertices is max-degree( G )-colorable" I Base case: n = 1 . If graph has only one node, then it cannot have any edges. Hence, it is 1-colorable.
