WebIn the mathematical discipline of graph theory, a graph labelling is the assignment of labels, traditionally represented by integers, to edges and/or vertices of a graph. [1] Formally, given a graph G = (V, E), a vertex labelling is a function of V to a set of labels; a graph with such a function defined is called a vertex-labeled graph. WebDec 9, 2015 · Euler proved that a given graph is a Euler graph if and only if all its vertices are of even degree. Proof: Suppose that a graph G is a Euler Graph, that means it has a closed walk which traces all the edges exactly once. If we closely observe, we find that at any vertex there are at least two edges which we have yet not traversed,”one going ...

WebJan 30, 2013 · The origin of graph theory started with the problem of Koinsber bridge, in 1735. Euler studied the problem of Koinsberg bridge and constructed a structure to solve the problem called Eulerian graph. In 1840, A.F Mobius gave the idea of complete graph and bipartite graph and Kuratowski proved that they are planar by means of recreational … WebMay 22, 2024 · Graph = set of vertices + set of edges or G = (V, E) Some key terms + definitions: Incident: x is incident to A and E. Any edge is incident to 2 vertices. Adjacent: G is adjacent to D, F, and H because there is some edge going from G to all these other vertices. Adjacent vertices are connected by an edge.
