AbstractBifurcation results are stated for the class of A-proper mappings whose proof uses the generalized degree theory of such operators. Applications of these results are described for two types of problem. The first is modelled on elliptic PDEs on unbounded domains, the second concerns periodic solutions of some ODEs. For the latter, several sets of hypotheses are discussed
