Convex pointed cone
WebRemark. Polar cone is always convex even if S is not convex. If S is empty set, S ∗ = R n. Polarity may be seen as a generalisation of orthogonality. Let C ⊆ R n then the orthogonal space of C, denoted by C ⊥ = { y ∈ R n: x, y = 0 ∀ x ∈ C }. WebExamples of convex cones Norm cone: f(x;t) : kxk tg, for a norm kk.
