A remark on bifurcation of Fredholm maps

Abstract

We modify an argument for multiparameter bifurcation of Fredholm maps by Fitzpatrick and Pejsachowicz to strengthen results on the topology of the bifurcation set. Furthermore, we discuss an application to families of differential equations parametrised by Grassmannians.
