Murty, M. S. N.; Apparao, B. V. Controllability and observability of Lyapunov systems. (English) Zbl 1103.93035 Ranchi Univ. Math. J. 32(2001), 55-65 (2004). Necessary and sufficient conditions for the controllability and observability of the time-varying linear Lyapunov systems are established. It is an extension of the well-known conditions for standard time-varying linear systems for the time varying Lyapunov systems.
