Fixed points of nonexpansive mappings in spaces of continuous functions
(American Mathematical Society, 2005)
Let K be a compact metrizable space and C(K) the Banach space of all real continuous functions defined on K with the maximum norm. It is known that C(K) fails to have the weak fixed point property for nonexpansive mappings ...

Relaciones entre operadores asociados a distintas medidas de no compacidad
(1993-09-13)
El objeto fundamental del trabajo es investigar las relaciones existentes entre operadores contractivos para distintas medidas de no compacidad en base a las propiedades geométricas del espacio subyacente, para ello se ...

The Jordan-von Neumann constants and fixed points for multivalued nonexpansive mappings
(Elsevier, 2006-08-15)
The purpose of this paper is to study the existence of fixed point for nonexpansive multivalued mappings in a particular class of Banach spaces. Furthermore, we demonstrate a relationship between the weakly convergent sequence ...

The τ-fixed point property for nonexpansive mappings
(1998)
Let X be a Banach space and τ a topology on X. We say that X has the τ-fixed point property (τ-FPP) if every nonexpansive mapping T defined from a bounded convex τ-sequentially compact subset C of X into C has a fixed ...

Continuous dependence for implicit differential equations in Banach spaces
(Universitat de Barcelona, 1980)
In this paper we derive an existence theorem for the implicit defferential equation F(t, x,x') = 0 ; x(to) = are where F is a β-Lipschitz or α-Lipschitz operator in the second variable. The existence of maximal and unlimited ...

Some questions in metric fixed point theory, by A. W. Kirk, revisited
(Springer Open, 2012-12)
In this survey, we comment on the current status of several questions in Metric Fixed Point Theory which were raised by W. A. Kirk in 1995.

Genericity of the fixed point property under renorming.
(2010-11-25)
Una aplicación T definida de un espacio métrico M en M se dice no expansiva si d(Tx, Ty) ≤d(x, y) para todo x, y ∈M. Diremos que un espacio de Banach X tiene la Propiedad Débil del Punto Fijo (w-FPP) si para toda aplicación ...
