Abstract
Consider the Royden compactification R* of a Riemannian nmanifold R, Γ = R*\R its Royden boundary, Δ its harmonic boundary and the elliptic differential equation Δu = Pu, P ≥ 0 on R. A regular Borel measure m^{P} can be constructed on Γ with support equal to the closure of Δ^{P} = {q ϵ Δ : q has a neighborhood U in R* with _{U}^{ʃ}_{ᴖR}^{P ˂ ∞ }}. Every enegyfinite solution to u (i.e. E(u) = D(u) + ^{ʃ}_{R}u^{2}P ˂ ∞, where D(u) is the Dirichlet integral of u) can be represented by u(z) = ^{ʃ}_{Γ}u(q)K(z,q)dm^{P}(q) where K(z,q) is a continuous function on ^{Rx} Γ . A _{P}^{~}_{E}function is a nonnegative solution which is the infimum of a downward directed family of energyfinite solutions. A nonzero _{P}^{~}_{E}function is called _{P}^{~}_{E}minimal if it is a constant multiple of every nonzero _{P}^{~}_{E}function dominated by it. THEOREM. There exists a _{P}^{~}_{E}minimal function if and only if there exists a point in q ϵ Γ such that m^{P}(q) > 0. THEOREM. For q ϵ Δ^{P} , m^{P}(q) > 0 if and only if m^{0}(q) > 0 .
