摘要：
<正> In this paper, we prove that every strongly continuous semigroup of bounded opera-tors on a Hilbert space may be extended to a strongly continuous semigroup of normal operatorson a larger Krein space. Several equivalent formulations for the case where the extension space is aPontrjagin space are given.
