Abstract
A mathemetical framework for a realistic quantum probability theory is presented. The basic elements of this framework are measurements and amplitudes. Definitions of the various concepts are motivated by guidelines from the path integral formalism for quantum mechanics. The operational meaning of these concepts is discussed. Superpositions of amplitude functions are investigated and superselection sectors are shown to occur in a natural way. It is shown that this framework includes traditional nonrelativistic quantum mechanics as a special case. Proofs of most of the theorems will appear elsewhere.
