Results obtained during this period of research include solving two approximate controllability problems, which were previously open. New treatments were provided for rederiving already known tests for Euclidean controllability. New conditions wer derived for spectral controllability and hence stabilizability much easier to handle than those previously known. An interesting link was brought to light between point wise degeneracy and the lack of approximate controllability in Hilbert defined approximate controllability and Popov reachability was clarified.
