Abstract : The present report attempts a systematic presentation and review of modern theories of the earth's rotation (precession, nutation, and polar motion) for a rigid earth, a purely elastic earth, and the Poincare model consisting of a rigid mantle and a liquid core. Emphasis is on the treatment of an elastic earth on the basis of Liouville's equation and on the consideration of the earth's rotation as an eigenvalue problem. (Author)
