Equações de evolução com laplaciano fracionário: existência, unicidade, estimativas Lp-Lq, conservação generalizada de energia e espalhamento
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2018-09-21)
In this thesis we study some sigma-evolution equations in the Petrowsky's sense. When the coefficients are constant we obtain Lp-Lq estimates for linear equations and apply them to obtain results of existence, uniqueness ...
Inequalities in Lp−1 for the extended Lp best approximation operator
(Elsevier Inc, 2012-09)
The best polynomial approximation operator was recently extended by one of the authors from Lp to Lp−1. In this paper, we study weak and strong inequalities for maximal operators related with the extended best polynomial ...
Best Lp-Approximant pair on small intervals
(Michigan State University Press, 2015-03)
In this paper we study the behavior of best Lp-approximations by algebraic polynomials pairs on union of intervals, when the measure of them tends to zero.
Diseño de una rejilla inclinada de bragg basada en fibra óptica de dos modos para reducción del retardo modal
(2022)
The capacity of multimode fiber optic networks is greatly diminished by differential modal delay with increasing speed or distance. The article contributes to this line and proposes an inclined Bragg grating made on a ...
