This volume contains review & research articles in a field of quantum chemical methodology: the theory of electron correlation & the localization problem. Correlation energy (i.e., the energy beyond the Hartree-Fock) plays an important role in the theoretical description of several chemical processes (reactions, excitations, ionization) while localization in quantum chemistry usually emerges as a mathematical transformation of the wave function. The connection between these two issues is provided by the need to evaluate correlation energy for larger molecules, which is much easier in terms of localized contributions. The articles selected discuss coupled cluster, perturbational & geminal-based schemes, & cover wave function as well as density based approaches.
