A corrector for the Sverdrup solution for a domain with islands
(Taylor & Francis, 2004-03)
In this paper we look at the influence of the Coriolis force on the quasi-geostrophic equations on a domain with islands. We prove that asymptotically we obtain the solution of the Sverdrup equation with homogeneous Dirichlet ...

Stability for nematic liquid crystals with stretching terms
(World Scientific, 2010)
We study a nematic crystal model appearing in [Liu et al.,2007] modeling stretching effects depending on the different shape of microscopic molecules of the material, under periodic boundary conditions. The aim of the ...

Local strong solution for the incompressible Korteweg model
(Elsevier, 2006-02)
We consider a Navier-Stokes type system with a Korteweg stress tensor, coupled with a concentration equation without diffusion. We give a result concerning the local in time existence (and uniqueness) of strong solution ...

On the uniqueness and regularity of the Primitive Equations imposing additional anisotropic regularity
(Elsevier, 2005-07)
In this note, we prove that given u a weak solution of the Primitive Equations, imposing an additional condition on the vertical derivative of the velocity u (concretely ∂zu ∈ L∞(0, T;L2(Ω)) ∩ L2(0, T; H1(Ω))), then two ...

Density-dependent incompressible fluids with non-Newtonian viscosity
(Institute of Mathematics, Czech Academy of Sciences, 2004)
We study the system of PDEs describing unsteady flows of incompressible fluids with variable density and non-constant viscosity. Indeed, one considers a stress tensor being a nonlinear function of the symmetric velocity ...

Global in time solutions for the Poiseuille flow of Oldroyd type in 3D domains
(Springer-Verlag, 2001-12)
A Poiseuille flow in a 3D cylindrical domain is considered for a non-newtonian fluid of Oldroyd type. We prove existence (and uniqueness) of a global (in time) weak solution. Moreover, this weak solution is an strong ...

Superconvergence in velocity and pressure for the 3D time-dependent Navier-Stokes equations
(Sociedad Española de Matemática Aplicada, 2012-01)
This work is devoted to the superconvergence in space approximation of a fully discrete scheme for the incompressible time-dependent Navier-Stokes Equations in three-dimensional domains. We discrete by Inf-Sup-stable Finite ...

Reproductivity for a nematic liquid crystal model
(2006-11)
In this paper we prove existence of weak solution with the reproductivity in time property, for a penalized PDE's system related to a nematic liquid crystal model. This problem is relatively explicit when time-independent ...

A note on a degenerate elliptic equation with applications for lakes and seas
(Texas State University, 2004)
In this paper, we give an intermediate regularity result on a degenerate elliptic equation with a weight blowing up on the boundary. This kind of equations is encountoured when modelling some phenomena linked to seas or ...
