Stackelberg-Nash exact controllability for linear and semilinear parabolic equations
(EDP Sciences, 2015)
This paper deals with the application of Stackelberg–Nash strategies to the control of parabolic equations. We assume that we can act on the system through a hierarchy of controls. A first control (the leader) is assumed ...

On the control of the Burgers-alpha model
(Project Euclid, 2013-09-15)
This work is devoted to proving the local null controllability of the Burgers- α model. The state is the solution to a regularized Burgers equation, where the transport term is of the form z y x , z = ( I d ...

Local Null Controllability of a Free-Boundary Problem for the Semilinear 1D Heat Equation
(Springer, 2016-08-15)
This paper deals with the local null control of a free-boundary problem for the 1D semilinear heat equation with distributed controls (locally supported in space) or boundary controls (acting at x=0). In the main result ...

Why viscous fluids adhere to rugose walls
(Elsevier, 2003-04-10)
The main purpose of this paper is to justify rigorously the following assertion: A viscous fluid cannot slip on a wall covered by microscopic asperities because, due to the viscous dissipation, the surface irregularities ...

Theoretical and numerical local null controllability of a Ladyzhenskaya-Smagorinsky model of turbulence
(Springer, 2015-12)
This paper deals with the control of a differential turbulence model of the Ladyzhenskaya–Smagorinsky kind. In the equations we find local and nonlocal nonlinearities: the usual transport terms and a turbulent viscosity ...

Null controllability of the heat equation with boundary Fourier conditions: the linear case
(Société de Mathématiques Appliquées et Industrielles, 2006-06-20)
In this paper, we prove the global null controllability of the linear heat equation completed with linear Fourier boundary conditions of the form . We consider distributed controls with support in a small set and nonregular ...

Existence and uniqueness results for a coupled problem related to the stationary Navier-Stokes System
(1997-04)
In this paper, we consider some systems which are close to the stationary Navier-Stokes equations. The structure of these systems is the following: An N-dimensional equation for motion, the incompressibility condition and ...
