Simulation of liquid structure in the border with a solid wall

Paper is devoted to the classical molecular systems in the framework of a model of liquid bordering on a perfectly smooth solid surface. The solution of the fundamental system of the Ornstein-Zernike equations is given. It is shown that the rarefied molecular system can be described as a transition from the axial to the sphere symmetry. The solution is obtained by decomposition of the distribution functions in powers of the density up to linear terms.
