The works of Ramsey on colorations and more specially the results obtained by Turán in 1941 was at the origin of another branch of graph theory, extremal graph theory. The four color problem remained unsolved for more than a century. WebA graph is a pictorial and mathematical representation of a set of objects where some pairs of objects are connected by links. The interconnected objects are represented by points termed as vertices or nodes and the links that connect the vertices are called edges or arcs or lines. In other words, a graph is an ordered pair G = (V, E) where, G ...

Graph theory is a field of mathematics about graphs. A graph is an abstract [disambiguation needed] representation of: a number of points that are connected by lines. Each point is usually called a vertex (more than one are called vertices ), and the lines are called edges.
