Dynamics and Symmetries,the reduced resolvent and derive a rigorous version of the Fermi golden rule. In Section 4 we discuss briefly how one may use symmetries to simplify the treatment of decay processes. The last section is devoted to space-time transformations. We show there the main features of the relativistically in

Pseudo-Hamiltonians,annel scattering processes. We derive some conditions under which this approximation may be expected to be good. Motivated by this problem, we present in the last section some fundamental notions of the non-unitary scattering theory.

Feynman Path Integrals,ection 2. Another ‘sequential’ definition of the Feynman path integral based on the product formulae is given in Section 5. The final section of this chapter contains more information about the other F-integral theories and their mutual relations.

Here we shall be concerned with the first approach, which is suitable primarily for a description of decay processes, absorption, etc. The second approach is used mostly for the treatment of various relaxation phenomen

The study of such situations is the main subject of this chapter. First we formulate the basic assumptions and derive the integral equ

First, we introduce the reduced resolvent and show the principal role played by its analytical structure, especially by poles of its analytic continuation. Section 2 is devoted to a detail
