PPT-Convex Hulls

Given a set of points x 1 y 1 x 2 y 2 x n y n the convex hull is the smallest convex polygon containing all the points Convex Hulls Given a set of points x 1 y. The following are equivalent is PSD ie Ax for all all eigenvalues of are nonnegative for some real matrix Corollary Let be a homogeneous quadratic polynomial Then for all if and only if for some Rudi Pendavingh TUE Semide64257nite matrices Con Consider all possible pairs of points in the set and consider the line segment connecting any such pair. All such line segments must lie entirely within the set.. Convex Set of Points. Convex –vs- Nonconvex. Problems in Ramsey theory typically ask a question of the form: "how many elements of some structure must there be to guarantee that a particular property will hold?“.
