Approximation of solutions of fractional diffusions in compact metric measure spaces
(Birkhauser Verlag Ag, 2017-12)
In this note we prove that the solutions to diffusions associated with fractional powers of the Laplacian in compact metric measure spaces can be obtained as limits of the solutions to particular rescalings of some non-local ...
Quem tem mais pontos, o círculo ou a reta?
(Universidade Federal do Rio Grande do NorteBrasilUFRNLicenciatura em Matemática, 2017-12-08)
This paper aims to enunciate and demonstrate important peculiar results that occur
in metric spaces. For this, it is used the bibliographical research, with which a study
and survey was made on the metric spaces, sequences ...
Fully dynamic metric access methods based on hyperplane partitioning
(PERGAMON-ELSEVIER SCIENCE LTD, 2011-06)
Metric access methods based on hyperplane partitioning have the advantage, compared to the ball partitioning-based ones, that regions do not overlap. The price is less flexibility for controlling the tree shape, especially ...

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 ...
Chaos induced by turbulent and erratic functions
(2009-12-01)
Let (X, d) be a compact metric space and f: X → X a continuous function and consider the hyperspace (K(X), H) of all nonempty compact subsets of X endowed with the Hausdorff metric induced by d. Let f̄: K(X) → K (X) be ...

Associative Memory in a Continuous Metric Space: A Theoretical Foundation
(Revista Computación y Sistemas; Vol. 13 No. 2, 2009-10-15)
Abstract We introduce a formal theoretical background, which includes theorems and their proofs, for a neural network model with associative memory and continuous topology, i.e. its processing units are elements of a ...
