Fixed point properties for semigroups of nonlinear mappings and amenability [PDF]

Journal of Functional Analysis, 2012
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 fixed point property for a semitopological semigroup of continuous mappings

A Note on Semigroups of Mappings on Banach Spaces

Journal of the Australian Mathematical Society, 1969
In a series of papers K. D. Magill, Jr. (see [1] and its references) has proved that, in various semigroups of mappings on topological spaces, every automorphism is inner, where an automorphism φ of a semigroup A is a bijection of A such that for all ƒ and g in A, and it is said to be inner if there exists a bijection h ∈ A such that h−1 (the inverse ...

The infinitesimal generators of semigroups of holomorphic maps

Annali di Matematica Pura ed Applicata (1923 -), 1992
Let \(X\) be a complex manifold. By \(\text{Hol}(X,X)\) we denote the space of holomorphic maps from \(X\) into inself. A one-parameter semigroup of holomorphic maps on \(X\) is a continuous map \(\varphi:\mathbb{R}^ +\to\text{Hol}(X,X)\) such that \(\varphi_ 0=\text{id}_ X\) and \(\varphi_ t\circ\varphi_ t=\varphi_{s+t}\) for all \(s,t\in\mathbb{R}^ +\

On the Ternary Semigroups of Continuous Mappings

2021
A ternary semigroup is a nonempty set with a ternary operation which is associative. In this paper, some properties of ternary semigroups are investigated and an abstract characterization of ternary semigroups of continuous mappings defined on ternary separated topological spaces is given.
