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…
Fixed Points Theorems in Hausdorff M-distance Spaces
Vladyslav Babenko, Vira Babenko, Oleg Kovalenko
We prove fixed point theorems in a space with a distance function that takes values in a partially ordered monoid. On the one hand, such an approach allows one to generalize some f…
