Dual Graph
... In the mathematical discipline of graph theory, the dual graph of a plane graph G is a graph that has a vertex corresponding to each face of G, and an edge joining two neighboring faces for each ... may also be used for more general embeddings of graphs on manifolds ...
... In graph theory, a subcoloring is an assignment of colors to a graph's vertices such that each color class induces a vertex disjoint union of cliques ... A subchromatic number χS(G) of a graph G is the least number of colors needed in any subcoloring of G ... Every proper coloring and cocoloring of a graph are also subcolorings, so the subchromatic number of any graph is at most equal to the cochromatic ...

One of the most common examples is the reduction of a general directed graph to an acyclic directed graph by contracting all of the vertices in each strongly connected component ...

Famous quotes containing the word graph:

    In this Journal, my pen is a delicate needle point, tracing out a graph of temperament so as to show its daily fluctuations: grave and gay, up and down, lamentation and revelry, self-love and self-disgust. You get here all my thoughts and opinions, always irresponsible and often contradictory or mutually exclusive, all my moods and vapours, all the varying reactions to environment of this jelly which is I.
    W.N.P. Barbellion (1889–1919)

    When producers want to know what the public wants, they graph it as curves. When they want to tell the public what to get, they say it in curves.
    Marshall McLuhan (1911–1980)
