A simple proof in Monge-Kantorovich duality theory

D. A. Edwards (2010)

Studia Mathematica

A simple proof is given of a Monge-Kantorovich duality theorem for a lower bounded lower semicontinuous cost function on the product of two completely regular spaces. The proof uses only the Hahn-Banach theorem and some properties of Radon measures, and allows the case of a bounded continuous cost function on a product of completely regular spaces to be treated directly, without the need to consider intermediate cases. Duality for a semicontinuous cost function is then deduced via the use of an...

A simple proof of a result of Abramovich and Wickstead

Zafer Ercan (2005)

Open Mathematics

The paper presents a simple proof of Proposition 8 of [2], based on a new and simple description of isometries between CD 0-spaces.

A simplification in the proof of the non-isomorphism between H¹(δ) and H¹(δ²)

Paul F. X. Müller (2002)

Studia Mathematica

The proof that H¹(δ) and H¹(δ²) are not isomorphic is simplified. This is done by giving a new and simple proof to a martingale inequality of J. Bourgain.

A simultaneous selection theorem

Alexander D. Arvanitakis (2012)

Fundamenta Mathematicae

We prove a theorem that generalizes in a way both Michael's Selection Theorem and Dugundji's Simultaneous Extension Theorem. We use it to prove that if K is an uncountable compact metric space and X a Banach space, then C(K,X) is isomorphic to C(𝓒,X) where 𝓒 denotes the Cantor set. For X = ℝ, this gives the well known Milyutin Theorem.
