The Kreps–Yan theorem for Banach ideal spaces
D. B. Rokhlin Southern Federal University, Faculty of Mathematics, Mechanics and Computer Sciences
Abstract:
Consider a closed convex cone $C$ in a Banach ideal space $X$ on some measure space with $\sigma$-finite measure. We prove that the fulfilment of the conditions $C\cap X_+=\{0\}$ and $C\supset-X_+$ guarantees the existence of a strictly positive continuous functional on $X$ whose restriction to $C$ is nonpositive.
Keywords:
Kreps–Yan theorem, Banach ideal space, $\sigma$-finite measure, cone, separation.
