This paper presents a simple methodology for building the generalized plant for the mixed sensitivity H, controlproblem, where the control object and the weighting functions for the sensitivity function may have poles on the imaginary axis. Our methodology shows that the ordinary assumptions made in
Every non-reflexive subspace of K(H), the space of compact operators on a Hilbert space H, contains an asymptotically isometric copy of c 0 . This, along with a result of Besbes, shows that a subspace of K(H) has the fixed point property if and only if it is reflexive.
