Existence of quadrature surfaces for positive measures with finite support

  • Henrik Shahgholian
Article

Abstract

Let μ be a positive measure with finite support in ℜ n (n≧2). Then we show that there is a bounded open set Ω, containing the support of μ, whose single-layer potential coincides with the potential of μ outside Ω.
