Abstract

Huang and Yang replace a hard core of radius c by their pseudopotential (HYPP), which can be used in perturbation theory. I show that HYPP and boundary value perturbation theory give the same energy shift, to first order in c. I model a two‐body potential as an oscillator potential (angular frequency ω) and a hard core. For an A‐body system, the ratio of the first order energy correction to the unperturbed energy is 0.448 A^3/4^ c a, where a = (M ω/2__h__)^1/2^.

The process of determining equations of motion of a system consisting of rigid bodies and springs is often extremely laborious. In this paper, a method is presented whereby all terms of a system of equations for planar ri.qid body systems are calculated systematically. It is assumed that the system

The paper presents the non-singular forms of Green's formula and its normal derivative of exterior problems for three-dimensional Laplace's equation. The main advantage of these modi"ed formulations is that they are amenable to solution by directly using quadrature formulas. Thus, the conventional b
