Null controllability for a parabolic-elliptic coupled system (Q360222)

The authors proved the null controllability for a parabolic-elliptic coupled system. The null controllability results are established by previously proving appropriate Carleman estimates for the solution to the associated adjoint system, and they also adapted a fixed point argument to get the null controllability results. Under appropriate assumptions, they proved the uniform null controllability property, and the convergence of the associated null control are established.
