摘要：

The infinitesimal generator A of a strongly continuous semigroup on a Hilbert space is assumed to satisfy that B-beta := A-beta is a sectorial operator of angle less than pi/2 for some beta >= 0. If B-beta is dissipative in some equivalent scalar product then the Naimark-Arocena representation theorem is applied to obtain a Krein space unitary dilation of the semigroup.
