Bifurcation results for critical points of families of functionals

Portaluri, Alessandro, Waterstraat, Nils (2014) Bifurcation results for critical points of families of functionals. Differential Integral Equations, 27 . pp. 369-386. ISSN 0893-4983.


Recently the first author studied the bifurcation of critical points of families of functionals on a Hilbert space, which are parametrised by a compact and orientable manifold having a non-vanishing first integral cohomology group. We improve this result in two directions: topologically and analytically. From the analytical point of view we generalise it to a broader class of functionals; from the topological point of view we allow the parameter space to be a metrisable Banach manifold. Our methods are in particular powerful if the parameter space is simply connected. As an application of our results we consider families of geodesics in (semi-) Riemannian manifolds.
