REMARK ON THE CONTROLLABILITY FOR SEMILINEAR EVOLUTION EQUATIONS
In this paper we deal with approximate controllability for semilinear system in a Hilbert space. In order to obtain the controllability, we assume that the system of the generalized eigenspaces of the principal operator is complete in the state space, which has a simple form and can be applied to …
