Measure of Noncompactness and Nondensely Defined Semilinear Functional Differential Equations with Fractional Order
(Universidad de La Frontera. Departamento de Matemática y EstadísticaUniversidade Federal de Pernambuco. Departamento de Matemática, 2010)
First-order system least-squares finite element method for singularly perturbed Darcy equations
(2023)
We define and analyse a least-squares finite element method for a first-order reformulation of a scaled Brinkman model of fluid flow through porous media. We introduce a pseudostress variable that allows to eliminate the ...
Generalized Thomas–Fermi equations as the Lampariello class of Emden–Fowler equations
(Elsevier Science BV, 2017)
On the solution of generalized equations and variational inequalities
(Universidad de La Frontera. Departamento de Matemática y EstadísticaUniversidade Federal de Pernambuco. Departamento de Matemática, 2011)
On necessary and sufficient conditions for strong hyperbolicity in systems with constraints
(IOP Publishing, 2020-09)
In this work, we study constant-coefficient first order systems of partial differential equations and give necessary and sufficient conditions for those systems to have a well-posed Cauchy problem. In many physical ...
Uniform exponential dichotomy and continuity of attractors for singularly perturbed damped wave equations
(Springer, 2006-07-01)
For eta >= 0, we consider a family of damped wave equations u(u) + eta Lambda 1/2u(t) + au(t) + Lambda u = f(u), t > 0, x is an element of Omega subset of R-N, where -Lambda denotes the Laplacian with zero Dirichlet boundary ...

Charged Brownian particles: Kramers and Smoluchowski equations and the hydrothermodynamical picture
(2011-05-01)
We consider a charged Brownian gas under the influence of external and non-uniform electric, magnetic and mechanical fields, immersed in a non-uniform bath temperature. With the collision time as an expansion parameter, ...

Algebraic functions in quasiprimal algebras
(Wiley VCH Verlag, 2014-04)
A function is algebraic on an algebra math formula if it can be implicitly defined by a system of equations on math formula. In this note we give a semantic characterization for algebraic functions on quasiprimal algebras. ...
