摘要 考虑一个在相空间具有非双曲非临界闭轨的n维自治系统的周期扰动系统,研究了该自治系统在空间(x,t)上的非双曲非临界不变环面的分支,得到了2个主要的结果. Consider the time-periodic perturbations of n - dimensional autonomous systems with nonhy- perbilic but noncritical closed orbits in the phase space. The elementary bifurcations to a nonhyperbilic but noncritical invariant torus of the unperturbed systems in the extended phase space ( x, t) are studied and two sets of conditions on bifurcations of the invariant tori are obtained.
