This work considers some exactly soluble lattice models in order to discuss modern methods and concepts in statistical mechanics. The behaviour of systems are illustrated as dilute antiferromagnets, spin glasses, and modulated magnets and alloys. Specific examples are included.

Time decays form the basis of a multitude of important and interesting phenomena in quantum physics that range from spectral properties, resonances, return and approach to equilibrium, to quantum mixing, and the "arrow of time". This monograph is devoted to a clear and precise, yet pedagogical account of the associated concepts and methods.
