  • Abstract
    In this paper the problem of optimal integration for fast oscillatory functions of two variables is solved constructively in the case where a priori information is limited. The connection of this problem with the problem of optimal recovery of a function from interpolational classes is analysed using properties of majorants and minorants for these functional classes.
