Otopy classification of gradient compact perturbations of identity in Hilbert space


Piotr Bartłomiejczyk, Piotr Nowak-Przygodzki




We prove that the inclusion of the space of gradient local maps into the space of all local maps from Hilbert space to itself induces a bijection between the sets of the respective otopy classes of these maps, where by a local map we mean a compact perturbation of identity with a compact preimage of zero.
