WebSperner's theorem, in discrete mathematics, describes the largest possible families of finite sets none of which contain any other sets in the family. It is one of the central results in extremal set theory.It is named after Emanuel Sperner, who published it in 1928..

First, we will prove the S-lemma in the homogeneous case. Theorem 2 (The homogeneous S-lemma). Consider the quadratic optimization problem: min. x xTBx (3) s.t. xTAx 0: Suppose 9 x s.t. x TAx> 0 and suppose that 8x, xTAx 0 implies xTBx 0. Then, 9 0; s.t. B A.
