Unique continuation principle for systems of parabolic equations
ESAIM: Control, Optimisation and Calculus of Variations, Tome 16 (2010) no. 2, pp. 247-274.

In this paper we prove a unique continuation result for a cascade system of parabolic equations, in which the solution of the first equation is (partially) used as a forcing term for the second equation. As a consequence we prove the existence of ε-insensitizing controls for some parabolic equations when the control region and the observability region do not intersect.
