Abstract-Themaximal (A, B) invariantsubspacecontained in kernel C´, where (A, B, C´) is associatedwith the standard linear system (l), is shown to be equal,when (A, B, C´) saW~es condition (6), to theintersec- tion of themaximal (A ,B ) invariant subspaces contained in kernel C;, i=l:.-,m,C,´denotingtheithrowofC´.
