Control Problems for Semilinear Neutral Differential Equations in Hilbert Spaces
We construct some results on the regularity of solutions and the approximate controllability for neutral functional differential equations with unbounded principal operators in Hilbert spaces. In order to establish the controllability of the neutral equations, we first consider the existence and reg...
