SOME REMARKS ON CONTROLLABILITY OF EVOLUTION EQUATIONS IN BANACH SPACES

Research output: Contribution to a Journal (Peer & Non Peer)Articlepeer-review

Abstract

In almost all papers in the literature, the results on exact controllability hold only for finite dimensional Banach spaces, since compactness of the semigroup and the bounded invertibility of an operator implies finite dimensional. In this note we show that the existence theory on controllability in the literature, can trivially be adjusted to include the infinite dimensional space setting, if we replace the compactness of operators with the complete continuity of the nonlinearity.
