Fixed point properties for semigroups of nonlinear mappings on unbounded sets
Anthony T. -M. Lau, Yong Zhang
A well-known result of W. Ray asserts that if is an unbounded convex subset of a Hilbert space, then there is a nonexpansive mapping : that has no fixed point. In t…
Algebraic and analytic properties of semigroups related to fixed point properties of non-expansive mappings
Anthony T. M. Lau, Yong Zhang
The purpose of this paper is to give an updated survey on various algebraic and analytic properties of semigroups related to fixed point properties of semigroup actions on a non-em…
Amenability properties of Banach algebra valued continuous functions
Reza Ghamarshoushtari, Yong Zhang
Let be a compact Hausdorff space and a Banach algebra. We investigate amenability properties of the algebra of all -valued continuous functions. We show that $C…
Amenability of Beurling algebras, corrigendum to a result in "Generalised notions of amenability, II"
Fereidoun. Ghahramani, Richard J. Loy, Yong Zhang
We fix a gap in the proof of a result in our earlier paper "Generalised notions of amenability, II" (J. Funct. Anal. 254 (2008) 1776-1810), and so provide a new proof to a characte…
Non-weakly amenable Beurling algebras
Varvara Shepelska, Yong Zhang
Weak amenability of a weighted group algebra, or a Beurling algebra, is a long-standing open problem. The commutative case has been extensively investigated and fully characterized…
Central Beurling algebras: Weak amenability of the central Beurling algebras on [FC] groups
Varvara Shepelska, Yong Zhang
We study weak amenability of central Beurling algebras . The investigation is a natural extension of the known work on the commutative Beurling algebra . For […
