Popis: In this paper we will generalize the Kalman rank condition for the null controllability to \begin{document}$n$\end{document} -coupled linear degenerate parabolic systems with constant coefficients, diagonalizable diffusion matrix, and \begin{document}$m$\end{document} -controls. For that we prove a global Carleman estimate for the solutions of a scalar \begin{document}$2n$\end{document} -order parabolic equation then we infer from it an observability inequality for the corresponding adjoint system, and thus the null controllability.
