Abstract: We study the stabilization problem of linear parabolic boundary control systems. While the control system is described by a pair of standard linear differential operators $ \left( {L, \tau } \right)$, the corresponding semigroup generator generally admits no Riesz basis of eigenvectors. Very little information on the fractional powers of this generator is needed. In this sense our approach has enough generality as a prototype to be used for other types of parabolic systems. We propose in this paper a unified algebraic approach to the stabilization of a variety of parabolic boundary control systems.
