Lorentz-Shimogaki and Boyd Theorems for weighted Lorentz spaces
(Oxford University Press, 2014-04)
We prove the Lorentz-Shimogaki and Boyd theorems for the spaces Λpu(w). As a consequence, we give the complete characterization of the strong boundedness of H on these spaces in terms of some geometric conditions on the ...
Characterization of the weak-type boundedness of the Hilbert transform on weighted Lorentz spaces
(Birkhauser Boston Inc, 2013-05)
We characterize the weak-type boundedness of the Hilbert transform H on weighted Lorentz spaces Lambda_p(u,w) , with p>0, in terms of some geometric conditions on the weights u and w and the weak-type boundedness of the ...

On the Heat Equation with Nonlinearity and Singular Anisotropic Potential on the Boundary
(2017-03-01)
This paper concerns with the heat equation in the half-space ℝ+n with nonlinearity and singular potential on the boundary ∂ℝ+n. We show a well-posedness result that allows us to consider critical potentials with infinite ...
Efeitos do campo magnético sobre processos de corrosão em aço AISI 1020
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2017-09-19)
In this dissertation the effects of the application of magnetic field during the electrochemical reactions of corrosion in samples of steel AISI 1020 in KNO_3 solution were investigated. The experiments were measurements ...
O problema de Björling para superfícies máximas no espaço de Lorentz-Minkowski L4
(2011-05-17)
Neste trabalho apresentamos uma representação tipo Weierstrass para superfícies máximas no espaço de Lorentz -Minkowski Ln . Baseado no trabalho de Asperti e Vilhena [5], consideramos esta
representação para o caso n = ...
Self-adjointness of two-dimensional Dirac operators on corner domains
(European Matjermatical, 2021)
We investigate the self-adjointness of the two-dimensional Dirac operator D, with quantum-dot and Lorentz-scalar delta-shell boundary conditions, on piecewise C-2 domains (with finitely many corners). For both models, we ...
Attitude stabilization of a rigid spacecraft in the geomagnetic field
(Elsevier B.V., 2007-01-01)
An analytical method is proposed to study the attitude stability of a triaxial spacecraft moving in a circular Keplerian orbit in the geomagnetic field. The method is developed based on the electrodynamics effect of the ...
