Theories of Nutation and Polar Motion II

Abstract

The report describes and interrelates various theories of nutation and polar motion based on an earth model consisting of an elastic mantle and a liquid core. In order to make basic features transparent and to facilitate interrelation and intercomparison, the liquid core is considered homogeneous and incompressible. A detailed treatment of the theory of Molodensky serves as a basis for describing recent advances by Shen and Mansinha, Smith, Wahr, and others; an elementary treatment of the variational approach by Jeffreys and Vicente and a numerical comparison conclude the report.
