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…
Characterisations of Fourier and Fourier--Stieltjes algebras on locally compact groups
Anthony To-Ming Lau, Hung Le Pham
Motivated by the beautiful work of M. A. Rieffel (1965) and of M. E. Walter (1974), we obtain characterisations of the Fourier algebra of a locally compact group in term…
A property for locally convex -algebras related to Property and character amenability
Xiao Chen, Anthony To-Ming Lau, Chi-Keung Ng
For a locally convex -algebra equipped with a fixed continuous -character , we define a cohomological property, called property , which is similar to…
Finie dimensional invariant subspace property and amenability for a class of Banach algebras
Anthony T. -M. Lau, Yong Zhang
Motivated by a result of Ky Fan in 1965, we establish a characterization of a left amenable F-algebra (which includes the group algebra and the Fourier algebra of a locally compact…
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…
