Weak amenability of commutative Beurling algebras

Yong Zhang

For a locally compact Abelian group $G$ and a continuous weight function $ω$ on $G$ we show that the Beurling algebra $L^{1} (G, ω)$ is weakly amenable if and only if there is no nont…

Fixed point properties for semigroups of nonlinear mappings and amenability

A. T. -M. Lau, Yong Zhang

In this paper we study fixed point properties for semitopological semigroup of nonexpansive mappings on a bounded closed convex subset of a Banach space. We also study a Schauder f…

Solved and unsolved problems in generalized notions of amenability for Banach algebras

Yong Zhang

We survey the recent investigations on (bounded, sequential) approximate amenability/contractibility and pseudo-amenability/contractibility for Banach algebras. We will discuss the…
