Abstract:
Nonlocal bifurcations of vector fields on the Klein bottle are studied. The problem is to construct a bifurcation scenario that corresponds to disappearance of a saddle-node cycle on the Klein bottle filled with homoclinic trajectories of this cycle. For the global Poincaré map specified by a unimodal function, a complete description of bifurcation scenarios is obtained. The bifurcation scenario corresponding to an arbitrary unimodal function is written out. Also, a classification of bifurcation scenarios that shows which of them can be realized in the unimodal case is given.
