Null-controllability for some linear parabolic systems with controls acting on different parts of the domain and its boundary

  • Guillaume Olive
Original Article


In this work, we study the null-controllability properties of linear parabolic systems with constant coefficients in the case where several controls are acting on different distributed subdomains and/or on the boundary. We prove a Kalman rank condition in the one-dimensional case. In the case where only distributed controls are considered, we also establish related results such as a Carleman estimate.
