Many equations have been introduced and derived by the author indicated inthe title in relation to multi-electron densities between the Hohenberg-Kohntheorems and variational principle, conversion of the non-relativisticelectronic Schrodinger equation to scaling correct moment functional of groundstate one-electron density to estimate ground state electronic energy,participation of electron-electron repulsion energy operator in thenon-relativistic electronic Schrodinger equation via the coupling strengthparameter along with generalizing the Hund rule, the emblematic theoremsvirial-, Moller-Plesset-, Hohenberg-Kohn-, Koopmans-, Brillouin theorem andconfiguration interactions formalism, and with analytic evaluation of Coulombintegrals for one, two and three-electron operators, as well as focusing onground state electronic energy, correlation energy and zero point energy ofstationer molecular systems.
