For integral operators on classes of functions with values in semilinear metric spaces, we obtain estimates of their deviations and discuss possible applications of these estimates to studying problems of approximation by generalized trigonometric polynomials, optimization of approximate integration formulas, and recovery of functions under the conditions of incomplete information.</p>}, number={5}, journal={Ukrainsâ€™kyi Matematychnyi Zhurnal}, author={Babenko V.
