Tyshko N. Electron liquid model's correlation effects accounting in the frames of the reference system approach

It was investigated the properties of n-partical correlation function of the reference system. At non zero temperatures the reference functions are represented as one-dimension Fermi integrals. It was solved the integral equation for dynamical local field correction function, and studied it's temperature dependence. It is proposed the potential regularisation method for short range electron correlations accounting by using effective electron interaction potential related to potential of interacting charged quantum packeges. It was improved the variant of collective description of electron liquid model that is proposed in the paper of Vavrukh M.V. and Slobodyan S.B., by using smooth similar to functions for spliting Coulomb potential in long-range and short-range parts.
