Controlabilité régionale du rotationel d'un système parabolique

Abstract

This work enters within the framework of mathematics applied for the differential equations to the derivative partial. The goal is to study the controllability of the rotational for a parabolic system. one took system distribute depends on the time, and one A studies the case where one can join the state of system of an initial state towards a state of a rotational a priori selected. Properties and characterizations were established; in particular the relation between the controllability and the structure of the actuators excite the system. The rotational operator that one introduced can be replaced by a linear differential operator of order one and has constant coefficients, in this case, all the established results remain valid with some differences.
