摘要
We use fixed point index methods to Study the set of forced oscillations in periodically perturbed systems of ODEs on manifolds. We prove the existence of branches of periodic solutions for a particular class of system where, contrary to the usual 'nondegeneracy' assumption, the leading vector field is neither trivial nor has a set of compact zeros.
