Corrections to "On the structure of H/sup /spl infin// control systems and related extensions"

The authors state that in the original paper (Kimura, Lu and Kawatani, ibid., vol. 36, p. 653-67, 1991) a lemma on (J,J')-losslessness is not correct. Its stated implications are also not fully correct. They give a counterexample to these claims and show how they can be fixed by strengthening the assumption.
