Bessel Potentials in Ahlfors Regular Metric Spaces
(Springer, 2016-08)
In this paper we introduce Bessel potentials and the Sobolev potential spaces resulting from them in the context of Ahlfors regular metric spaces. The Bessel kernel is defined using a Coifman type approximation of the ...
GEOMETRIC RELATIONS BETWEEN SPACES OF NUCLEAR OPERATORS AND SPACES OF COMPACT OPERATORS
(AMER MATHEMATICAL SOCPROVIDENCE, 2012)
We extend and provide a vector-valued version of some results of C. Samuel about the geometric relations between the spaces of nuclear operators N(E, F) and spaces of compact operators K(E, F), where E and F are Banach ...
Banach spaces without minimal subspaces
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
We prove three new dichotomies for Banach spaces a la W.T. Gowers` dichotomies. The three dichotomies characterise respectively the spaces having no minimal subspaces, having no subsequentially minimal basic sequences, and ...

On Newton-Sobolev spaces
(Kossuth Lajos Tudomanyegyetem, 2017-01)
Newton-Sobolev spaces, as presented by N. Shanmugalingam, describe a way to extend Sobolev spaces to the metric setting via upper gradients, for metric spaces with ´sucient´ paths of nite length. Sometimes, as is the case ...
On Lipschitz-free spaces over spheres of Banach spaces
(Richard Aron, 2021)
We prove that, for each Banach space X which is isomorphic to its hyperplanes, the Lipschitz-free spaces over X and over its sphere are isomorphic.
Review on space weather in Latin America. 3. Development of space weather forecasting centers
(Elsevier, 2016-03)
The present work is the third of a three-part review of space weather in Latin America, specifically observing its evolution in three countries (Argentina, Brazil and Mexico). This work presents the decision process for ...
