In this paper we present a systematic method which computes bounds for invariant subspaces belonging to a double or nearly double eigenvalue. Furthermore an algorithm based on interval arithmetic tools is introduced which improves these bounds systematically. In dieser Arbeit bringen wir eine systematische Methode zur Berechnung von Schranken für invariante… CONTINUE READING
