Abstract

We consider a one-dimensional 2 × 2 parabolic equations, simultaneously controllable by a localized function in their source term. We also consider a simultaneous boundary control. In each case, we prove the existence of minimal time T₀(q) of null controllability, that is to say, the corresponding problem is null controllable at any time T > T₀(q) and not null controllable for T < T₀(q). We also prove that one can expect any minimal time associated to the boundary control problem.
