WebLet n = 5. The chromatic number of C5 is 3. A coloring of C5 using three colors. 11. 11 Application of Graph Colorings Graph coloring has a variety of applications to problems involving scheduling and assignments. Note that no efficient algorithm is known for graph coloring, this does not lead to efficient algorithms for scheduling and assignments. WebChromatic Polynomials for Graphs. The chromatic polynomial of a graph G is the polynomial C G ( k) computed recursively using the theorem of Birkhoff and Lewis. The theorem of Birkhoff and Lewis states: c G ( k) = c G − e ( k) − c G / e ( k) where e is any edge from G, and. G − e is the graph obtained from G by removing edge e.

WebGraph theory is the study of dots and lines: sets and pairwise relations between their elements. Deﬁnition. A graph G is an ordered pair (V(G), E(G)), where V(G) is a set of vertices, E(G) is a set of edges, and a edge is said to be incident to one or two vertices, called its ends. If e is incident to vertices u and v, we write e = uv = vu.

WebIn the mathematical field of graph theory, an automorphism of a graph is a form of symmetry in which the graph is mapped onto itself while preserving the edge– vertex connectivity.
