Abstract
Asymptotic formulas are derived for distribution functions and components of the pressure tensor for a Van der Waals fluid in a conelike cage of a solid. The formulas describe the local behavior of the fluid far from the vertex of the cone and at rather large distances from solid walls. It is shown that, due to the symmetry of the system, three diagonal components and one off-diagonal component of the pressure tensor differ from zero. The effect of the deviation of conelike pore walls from a cylindrical shape on the appearance of a noticeable contribution to the local characteristics of the fluid in the pore is estimated.
