Abstract

In the first part of this book, we have described an approach to the treatment of unstable quantum systems from a fundamentally new point of view, although the methods we have used have their source in the older work of Nagy and Foias (Nagy 1976), for which a system with exact semigroup evolution on a Hilbert space is embedded in a larger space in which the evolution is unitary. Projection back to the smaller space, a subspace of the larger space, then has exact semigroup evolution.
