Abstract
We present a formalism that represents pure states, mixtures and generalize d states as functionals on an algebra containing the observables of the sys tem. Along these states, there are other functionals that decay exponential ly at all times and therefore can be used to describe resonance phenomena. (C) 2001 Published by Elsevier Science B.V.
