ELEMENTARY BIFURCATIONS OF NONHYPERBOLIC INVARIANT TORI

WU Ran chao (Department of Mathematics and Physics, Anhui University of Technology, Ma'anshan 243032, China)  
Consider the time periodic perturbations of an n dimensional autonomous system with a nonhyperbolic orbit. By the method of averaging and Floquet theory, the bifurcations of the nonhyperbolic invariant torus in the extended phase space are studied.
