This paper is concerned with the study of the static charge susceptibility and correlation function of the charge density in the two-dimensional \(t\)-\(J\)-\(V\) model. A key role in this analysis is played by the method of equations of motion for the relaxation functions of the Hubbard operators. The main result establishes the dependence of the susceptibility and correlation functions on the hole concentration and temperature.
