Exposed point

In mathematics, an exposed point of a convex set is a point at which some continuous linear functional attains its strict maximum over . Such a functional is then said to expose . There can be many exposing functionals for . The set of exposed points of is usually denoted . A stronger notion is that of strongly exposed point of which is an exposed point such that some exposing functional of attains its strong maximum over at , i.e. for each sequence we have the following implication: . The set of all strongly exposed points of is usually denoted . There are two weaker notions, that of extreme point and that of of . * v * t * e (Wikipedia).
