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
Sperner family — In combinatorics, a Sperner family (or Sperner system), named in honor of Emanuel Sperner, is a set system (F, E) in which no element is contained in another. Formally, If X, Y are in F and X ≠ Y, then X is not contained in Y and Y is not… … Wikipedia
Dinitz conjecture — In combinatorics, the Dinitz conjecture is a statement about the extension of arrays to partial Latin squares, proposed in 1979 by Jeff Dinitz, and proved in 1994 by Fred Galvin. The Dinitz conjecture, now a theorem, is that given an n × n square … Wikipedia
