## Abstract A method of calculation of the correlation energy is proposed, which includes the superposition of configurations and the two particle approach. This method is based on the density matrix formalism. The approximate, but __N__βrepresentable expressions for the reduced density matrices ar

## Abstract The screened Coulomb potential following from the quadratic response theory is modified and applied to the Kahana equation for a positron in an electron gas. Electronβelectron correlations are taken into account in a local way, proposed by Shaw. For the first time within this formalism
A brief account is given of the origin and development of the electron theory and its successful application to improving physical and mechanical properties of a range of materials, including hard metals, metal-ceramic bonding, intermetallics and steels. As the nature of the bonding in solids, i.e.
