On the perturbations of maps obeying Shannon–Whittaker–Kotel’nikov’s theorem generalization

Let f : R?R be a map and t ? R+. The map f obeys the Shannon–Whittaker–Kotel’nikov theorem generalization (SWKTG) if f (t) = lim n?8 (k?Z f 1n ( k t ) sinc(t t – k))n for every t ? R. The aim of the present paper is to characterize the perturbations of the map f that obeys SWKTG. Our results enlarge...

Descripción
Sumario:Let f : R?R be a map and t ? R+. The map f obeys the Shannon–Whittaker–Kotel’nikov theorem generalization (SWKTG) if f (t) = lim n?8 (k?Z f 1n ( k t ) sinc(t t – k))n for every t ? R. The aim of the present paper is to characterize the perturbations of the map f that obeys SWKTG. Our results enlarge the catalog of maps that can be recomposed using SWKTG. We underline that maps obeying SWKTG play a central role in applications to chemistry and signal theory between other fields.
