**linear functional**on a linear topological space separates two sets , one of which has an interior point , then the functional is continuous . Proof . Let X be a linear topological space , and A1 , A , C X. Let h be a linear ...Page 452

If K is a closed cone with vertex p in a real locally convex linear topological space X , and K + X , then there exists a nonzero continuous

If K is a closed cone with vertex p in a real locally convex linear topological space X , and K + X , then there exists a nonzero continuous
