AB - UDC 517.5In this paper, we develop the theory of approximations in functional semilinear metric spaces, which allows us to consider classes of multi- and fuzzy-valued functions, as well as classes of Banach space-valued functions including classes of random processes. 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.
