On the Regularity for Some Class

We consider the weak regularity problem of posed-well-p L linear systems () ∞ < ≤ p 1 in Banach state spaces when its associated unbounded controllers take values in the extrapolated Favard class. We prove that this type of posed-well-p L linear systems are weakly regular and this regularity is output operators independent up to the well-posedness, provided the associated state spaces are non-r...

On the regularity condition for decomposable communication channels

A detailed analysis of the condition of regularity as stated in [1] for the validity of the theorem on £-capacity of decomposable channel is given, and some of its modifications are considered. One of the purposes of this paper is also to show how the regularity condition of [1] may be weakened. Some facts used in Part I of [1] without explicit proofs are established in Lemmas I and II.
