Let A be the generator of a strongly continuous semigroup T on the Hilbert space X , and let C be a linear operator from D(A) to another Hilbert space Y (possibly unbounded with respect to X , not necessarily admissible). We consider the problem of estimating the initial state z 0 โ D(A) (with respe
