An application methodology of locally conjugate operators improving the theory itself on an abstract level to cover known results in spectral and scattering theory. The volume is a self-contained presentation of real interpolation theory and an advance study of multi-parameter CO-groups, their functional calculi and the scales of Besov spaces associated with them. Also included is coverage devoted to commutator expansion, and a new algebraic framework for the N-body problem, and spectral properties of N-body Hamiltonians. Contains complete computation illustrations. Annotation c. by Book News, Inc., Portland, Or.
