21Degeneracy (graph theory) — In graph theory, a k degenerate graph is an undirected graph in which every subgraph has a vertex of degree at most k: that is, some vertex in the subgraph touches k or fewer of the subgraph s edges. The degeneracy of a graph is the smallest… …
22Skew-symmetric graph — In graph theory, a branch of mathematics, a skew symmetric graph is a directed graph that is isomorphic to its own transpose graph, the graph formed by reversing all of its edges. The isomorphism is required to be an involution without any fixed… …
23Independent set (graph theory) — The nine blue vertices form a maximum independent set for the Generalized Petersen graph GP(12,4). In graph theory, an independent set or stable set is a set of vertices in a graph, no two of which are adjacent. That is, it is a set I of vertices …
24Circle graph — For the chart, see Pie chart. A circle with five chords and the corresponding circle graph. In graph theory, a circle graph is the intersection graph of a set of chords of a circle. That is, it is an undirected graph whose vertices can be… …
25Circular-arc graph — A circular arc graph (left) and a corresponding arc model (right). In graph theory, a circular arc graph is the intersection graph of a set of arcs on the circle. It has one vertex for each arc in the set, and an edge between every pair of… …
26Cubic graph — Not to be confused with graphs of cubic functions. The Petersen graph is a Cubic graph …
27Continuous-time quantum walk — A Continuous time quantum walk (CTQW) is a walk on a given connected graph that is dictated by a time varying unitary matrix that relies on the Hamiltonian of the quantum system and the adjacency matrix. CTQW belongs to what is known as Quantum… …
28Outerplanar graph — A maximal outerplanar graph and its 3 coloring. In graph theory, an undirected graph is an outerplanar graph if it can be drawn in the plane without crossings in such a way that all of the vertices belong to the unbounded face of the drawing.… …
29Scene graph — A scene graph is a general data structure commonly used by vector based graphics editing applications and modern computer games. Examples of such programs include AutoCAD, Adobe Illustrator, Acrobat 3D, OpenSceneGraph and CorelDRAW.The scene… …
30Chordal graph — A cycle (black) with two chords (green). As for this part, the graph is chordal. However, removing one green edge would result in a non chordal graph. Indeed, the other green edge with three black edges would form a cycle of length four with no… …
