Curvature corrections to surface tension.
The paper studies the size dependence of the surface tension at a weakly curved liquid-vapor interface. Statistical expressions for the first and the second corrections to the surface tension are derived with the use of expansion of the first of the equations of the hierarchy of Born-Green-Yvon into a series in terms of the curvature of the dividing surface. A method of approximate evaluation of the second correction by information on the properties of a planar liquid-vapor interface is suggested.
