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. Equivalently, a Sperner family is an antichain in the inclusion lattice over the power set of E. A Sperner family is also sometimes called an independent system or a clutter.

Famous quotes containing the word family:

    English people apparently queue up as a sort of hobby. A family man might pass a mild autumn evening by taking the wife and kids to stand in the cinema queue for a while and then leading them over for a few minutes in the sweetshop queue and then, as a special treat for the kids, saying “Perhaps we’ve time to have a look at the Number Thirty-One bus queue before we turn in.”
    Calvin Trillin (b. 1940)
