报告摘要In this talk we talk about the bifurcations of tangent points of any degeneracy and tangent loops. We not only provide a functional function method for clarifying the recurrences but also combine this method and Poincare return map, and hence establish the relationships between the degeneracy and the numbers of crossing limit cycles and sliding loops bifurcating from tangent loops.
