Stechkin's problem for functions of a self-adjoint operator in a Hilbert space, Taikov-type inequalities and their applications
Vladyslav Babenko, Yuliya Babenko, Nadiia Kriachko
In this paper we solve the problem of approximating functionals (where is some function of self-adjoint operator ) on the class of elements of a Hilbert spac…
