Abstract: | In this paper, we prove that every strongly continuous semigroup of bounded operators on a Hilbert space may be extended to
a strongly continous semigroup of normal operators on a larger Krein space. Several equivalent formulations for the case where
the extension space is a Pontrjagin space are given. |
