Bifurcation of critical points for continuous families of C^2 functionals of Fredholm type

Jacobo Pejsachowicz, Nils Waterstraat

Given a continuous family of C^2 functionals of Fredholm type, we show that the non-vanishing of the spectral flow for the family of Hessians along a known (trivial) branch of crit…
