The Stokes equations with Fourier boundary conditions on a wall with asperities
(John Wiley & Sons, 2001-03)
We study the effect of the rugosity of a wall on the solution of the Stokes system complemented with Fourier boundary conditions. We consider the case of small periodic asperities of size ". We prove that the velocity ...

A geometric inverse problem for the Boussinesq system
(American Institute of Mathematical Sciences, 2006-11)
In this work we present some results for the inverse problem of the identification of a single rigid body immersed in a fluid governed by the stationary Boussinesq equations. First, we establish a uniqueness result. Then, ...

Global Carleman inequalities for parabolic systems and applications to controllability
(Society for Industrial and Applied Mathematics, 2006)
This paper has been conceived as an overview on the controllability properties of some relevant (linear and nonlinear) parabolic systems. Specifically, we deal with the null controllability and the exact controllability ...

Analysis of a two-phase field model for the solidification of an alloy
(ScienceDirect, 2009-03-09)
In this paper we present some theoretical results for a system of nonlinear partial differential equations that provide a phase field model for the solidification/melting of a metallic alloy. It is assumed that two different ...
