The Lagrange topPhysically, the Lagrange top is a symmetric rigid body spinning about its figure axis whose base point is fixed. A constant vertical gravitational force acts on the center of mass of the top, which lies on its symmetry axis.

Systems with SymmetryIn this chapter we discuss Hamiltonian systems with symmetry. By a symmetry of a Hamiltonian system (H, ., .) we mean a proper action of a Lie group G on a symplectic manifold (., .), which has a momentum mapping .: . → g*, and preserves the Hamiltonian ..

Action-angle coordinatesHere we prove the existence of local action angle coordinates for a Liouville integrable Hamiltonian system near a compact connected fiber of its integral mapping.

Geodesics on ,,verns the motion of two bodies in .. under gravitational attraction. We give two methods to regularize the flow of the Kepler vector field: one energy surface by energy surface and the other for all negative energies at once.

Basic Morse Theoryh manifold and show that if it is nondegenerate then there are local coordinates in which the function is equal to its second derivative. We also prove the Morse isotopy lemma which gives a criterion when two suitable level sets of a smooth function are diffeomorphic. We conclude the chapter by exte
