Abstract:

A general index theory for Lie group actions is developed which applies in particular to subsets of a Banach space which are invariant under the action of a compact Lie group G. Important special cases occur when G is Z2 or Ssuperscript 1. This theory should be useful for problems involving differential equations which are invariant under G, in particular in obtaining estimates for the the number of solutions of these equations. As an application a bifurcation problem for Hamiltonian systems of ordinary differential equations is studied and estimates are made on the number of periodic solutions bifurcating from an equilibrium solution.
