To prove this, we represent people as And in a more general setting this is known as a handshaking lemma. The real life statement of this lemma is by following, so before a business meeting some of its members shook hands. Now what we claim is that the number of people who shook an odd number of hands is always even. This conclusion is often called Handshaking lemma. When people in a meeting is represented by vertices, and shaking hand between two people represented by an edge, then the total number of hands shaken is equal to double the number of handshakes.

Handshaking lemma has an obvious "application" to counting handshakes at a party. It is also very useful in proofs and in general graph theory. I can't think of a concrete important example though, easy to explain within a short time. Any ideas about handshaking lemma or similar examples would be appreciated.

In any graph, The sum of degree of all the vertices is always even. 2011-09-20 · In 2009, I posted a calculational proof of the handshaking lemma, a well-known elementary result on undirected graphs.

Both results were proven by Leonhard Euler ( 1736 ) in his famous paper on the Seven Bridges of Königsberg that began the study of graph theory.

To prove this, we represent people as The handshaking lemma is one of the important branches of graph theory. The content is widely applied in topology and computer science. The basis of the development of the dyeing theory used in this research paper is to discuss the application of the right transfer method in dyeing theory.
