Abstract: The class of convolution equations on a large expanding interval is considered. The equations are characterized by the fact that the symbol of the corresponding operator has zeros or poles of the non-integer power in the dual variable, which leads to long-range influence. The power-order complete asymptotic expantions for kernel of the inverse operator while length of the interval tends to infinity is found.

Key words and phrases: semiclassical asymptotics, singular integral equations, Wiener–Hopf method, Schwartz alternating method.
