报告题目：Shrimps near homoclinic bifurcations
报告摘要：We show that, for any C^r (r>2) flow having a homoclinic loop to a saddle focus equilibrium, one can obtain a periodic orbit having two homoclinic tangencies by an arbitrarily small perturbation, which leads to the appearance of shrimps in the parameter plane. The same result also holds for diffeomorphisms having a homoclinic tangency.
