Analysis of third order linear analytic differential equations with a regular singularity: bessel and other classical equations
(International Press, Inc.PE, 2021-10-06)
We study third order linear differential equations with analytic coefficients under the viewpoint of explicitly constructing solutions and studying their convergence. We consider both homogeneous and non-homogeneous cases. ...

An elliptic singular system with nonlocal boundary conditions
(Elsevier, 2012-10)
We study the existence of solutions for the nonlinear second order elliptic system ∆u + g(u) = f(x), where g ∈ C(R N \ S, R N ) with S ⊂ R N bounded. Using topological degree methods, we prove an existence result under a ...
Global analysis of the dynamics of a mathematical model to intermittent HIV treatment
(Springer, 2020-07-09)
The aim of this paper is to study the qualitative dynamics of a piecewise smooth system modeling the intermittent treatment of the human immunodeficiency virus. Typical singularities and closed orbits are observable, and ...
Singular-ended spline interpolation for two-dimensional boundary element analysis
(John Wiley & Sons LtdW SussexInglaterra, 2000)
Differential transforms in weighted spaces
(Birkhauser Boston Inc, 2006-02)
We extend the results by Jones and Rosenblatt about the series of the differences of differentiation operators along lacunary sequences to BMO and to the setting of weighted Lp spaces. We use a different approach which ...
The relationship between South Atlantic SST and SACZ intensity and positioning
(SpringerHeidelberg, 2014)
This study explores the ocean–atmosphere
interaction in the formation and dynamics of the South
Atlantic Convergence Zone (SACZ), through the analysis
of the heat sources estimated through the outgoing longwave
radiation. ...
On the energy functionals derived from a non-homogeneous p-Laplacian equation: Γ-convergence, local minimizers and stable transition layers
(2020-03-15)
In this paper we consider a family of singularly perturbed non-homogeneous p-Laplacian problems ϵpdiv(k(x)|∇u|p−2∇u)+k(x)g(u)=0 in Ω⊂Rn subject to Neumann boundary conditions. We establish the Γ-convergence of the energy ...
