Beschreibung:
This book addresses two major classes of theories of electron correlation: the many-body perturbation theory and coupled cluster methods. It discusses the issues related to the formal development and consequent numerical implementation of multi-reference coupled cluster and perturbation theories from the standpoint of a practicing theoretician. The book emphasizes theoretical details and related algebraic and diagrammatic derivations. It covers basic issues of electron correlation problems, such as perturbation theory and coupled cluster methods.
