PROPAGATORS AND DILATIONS ON PSEUDO-HILBERT SPACES
Journal Title: Journal of Science And Arts - Year 2011, Vol 15, Issue 2
Abstract
In this paper we shall try to transpose the conditions of the existence of propagators for kernel on *-semigroups, notion introduced by P. Masani [6]. We will start with a few additional observations concerning *-representations and then we will present some properties of propagators and dilations.
