报告题目：Multiple chaos arising from single-parametric perturbation of a degenerate homoclinic orbit

报告摘要：We investigate multiple existence of homoclinic solutions for a periodically perturbed $N$-dimensional autonomous differential equation with a degenerate homoclinic solution of degeneracy degree $d$.Known results were obtained with a functional perturbation,which is regarded as an infinite-dimensional parameter.
