Abstract

The Green's function G ( x, ξ, λ ) associated with the differential equation is of importance in the theory of the expansion of an arbitrary function in terms of the solutions of the differential equation. It is proved that this function is unique if q ( x ) ≧ — Ax 2 — B , where A and B are positive constants or zero. A similar theorem is proved for the Green's function G ( x, y , ξ, η, λ ) associated with the partial differential equation
