In this paper, we consider general [italic]S¹-actions, which may differ on the domain and on the range, with isotropy subspaces with one dimension more on the domain. In the special case of self-maps the [italic]S¹-degree is given by the usual degree of the invariant part, while…

Bifurcation theory is the study of small solutions of nonlinear equations, depending on a number of parameters, when for certain values of these parameters more than one solution may appear. Because of the difficulties encountered in obtaining explicit solutions to such problems…
