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 transparant 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.
