   <dc:title>A uniqueness theorem for a Robin boundary value problem of Physical Geodesy</dc:title>
   <dc:creator>Otero Juez, Jesús</dc:creator>
   <dcterms:abstract>We get a uniqueness theorem for a Robin type boundary value problem for the Laplace equation arising in Physical Geodesy in the context of the gravimetric determination of the geoid. The boundary is an oblate ellipsoid of revolution and we have uniqueness of solutions provided that its eccentricity is (approximately) less than 0.526428.</dcterms:abstract>
