Some optimal recovery problems for operators on classes of -space valued functions

V. Babenko, V. Kolesnyk, O. Kovalenko

We solve three optimal recovery problems for operators on classes of -space (which is a semilinear metric space with two additional axioms that connect the metric with the algeb…

On approximation of hypersingular integral operators by bounded ones

Vladyslav Babenko, Oleg Kovalenko, Nataliia Parfinovych

We solve the Stechkin problem about approximation of generally speaking unbounded hypersingular integral operators by bounded ones. As a part of the proof, we also solve several re…

V. Babenko, A. Ligun, S. Spektor

We are proving a Bernstein type inequality in the shift-invariant spaces of .
