Genericity of the fixed point property under renorming.
(2010-11-25)
Una aplicaci on T de nida de un espacio m etrico M en M se dice no expansiva si d(Tx; Ty) d(x; y) para todo x; y 2 M. Diremos que un espacio de Banach X tiene la Propiedad D ebil del Punto Fijo (w-FPP) si para toda aplicaci ...

Compositions and convex combinations of asymptotically regular firmly nonexpansive mappings are also asymptotically regular
(Springer, 2012)
Because of Minty’s classical correspondence between firmly nonexpansive mappings and maximally monotone operators, the notion of a firmly nonexpansive mapping has proven to be of basic importance in fixed point theory, ...

The ε-entropy of some infinite dimensional compact ellipsoids and fractal dimension of attractors
(American Institute of Mathematical Sciences, 2017-09)
We prove an estimation of the Kolmogorov ε-entropy in H of the unitary ball in the space V, where H is a Hilbert space and V is a Sobolev-like subspace of H. Then, by means of Zelik’s result, an estimate of the fractal ...

Compositionally universal entire functions on the plane and the punctured plane
(Springer, 2013-06)
Necessary/sufficient conditions for a sequence of automorphisms of the complex plane to generate a sequence of composition operators that is universal on the punctured plane are provided. As a consequence, it is derived ...

A new quantitative two weight theorem for the Hardy-Littlewood maximal operator
(American Mathematical Society, 2015-02)
A quantitative two weight theorem for the Hardy-Littlewood maximal operator is proved improving the known ones. As a consequence a new proof of the main results in [HP] and in [HPR12] is obtained which avoids the use of ...

Sharp affine Sobolev type inequalities via the Lp Busemann–Petty centroid inequality
(Elsevier, 2016-07-15)
We show that the Lp Busemann-Petty centroid inequality provides an elementary and powerful tool to the study of some sharp affine functional inequalities with a geometric content, like log-Sobolev, Sobolev and Gagliardo-Nirenberg ...
