Amenable Crossed Product Banach Algebras Associated with a Class of -Dynamical Systems

M de Jeu, R El Harti, PR Pinto - Integral Equations and Operator Theory, 2017 - Springer
We prove that the crossed product Banach algebra ℓ^ 1 (G, A; α) ℓ 1 (G, A; α) that is
associated with a\mathrm C^* C∗-dynamical system (A, G, α)(A, G, α) is amenable if G is a …

This paper gives the concept of the reduced pro-Banach algebra crossed product
associated with inversely pro-Banach algebra dynamical system, and shows that the …

[HTML][HTML] Strong Klee–Andô Theorems through an Open Mapping Theorem for cone-valued multi-functions

M Messerschmidt - Journal of Functional Analysis, 2018 - Elsevier
A version of the classical Klee–Andô Theorem states the following: For every Banach space
X, ordered by a closed generating cone C⊆ X, there exists some α> 0 so that, for every x∈ …

[PDF][PDF] Positive representations on ordered Banach spaces

HJM Messerschmidt - 2013 - math.leidenuniv.nl
