• Critical graph — In general the notion of criticality can refer to any measure. But in graph theory, when the term is used without any qualification, it almost always refers to the chromatic number of a graph. Critical graphs are interesting because they are the… …   Wikipedia

• Graph coloring — A proper vertex coloring of the Petersen graph with 3 colors, the minimum number possible. In graph theory, graph coloring is a special case of graph labeling; it is an assignment of labels traditionally called colors to elements of a graph… …   Wikipedia

• Critical point (mathematics) — See also: Critical point (set theory) The abcissae of the red circles are stationary points; the blue squares are inflection points. It s important to note that the stationary points are critical points, but the inflection points are not nor are… …   Wikipedia

• Matching (graph theory) — In the mathematical discipline of graph theory, a matching or independent edge set in a graph is a set of edges without common vertices. It may also be an entire graph consisting of edges without common vertices. Covering packing dualities… …   Wikipedia

• Dominator (graph theory) — For Dominating set problem, see Dominating set. In computer science, in control flow graphs, a node d dominates a node n if every path from the start node to n must go through d. Notationally, this is written as d dom n (or sometimes d n). By… …   Wikipedia

• String graph — In graph theory, a string graph is an intersection graph of curves in the plane; each curve is called a string . Given a graph G , G is a string graph if and only if there exists a set of curves, or strings, drawn in the plane such that no three… …   Wikipedia

• Edge coloring — A 3 edge coloring of the Desargues graph. In graph theory, an edge coloring of a graph is an assignment of “colors” to the edges of the graph so that no two adjacent edges have the same color. For example, the figure to the right shows an edge… …   Wikipedia

• Mycielskian — In the mathematical area of graph theory, the Mycielskian or Mycielski graph of an undirected graph G is a graph μ(G) formed from G by a construction of Jan Mycielski (1955), who used it to show that there exist triangle free graphs with… …   Wikipedia
