Complete order amenability of the Fourier algebra. (English) Zbl 1217.43001
The authors define complete order amenability and first-order cohomology groups for quantized Banach ordered algebras. Let $G$ be a locally compact group. Then the Fourier algebra $A(G)$ is a quantized Banach ordered algebra. It is proved that $A(G)$ is complete order amenable if and only if $A(G)$ is operator amenable. The authors also show that all complete order derivations from $A(G)$ to any dual Banach completely ordered $A(G)$-bimodule are inner if and only if $A(G)$ is operator amenable.
