Summary: A 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 a noninteger power order in the dual variable, which leads to long-range influence. A power-order complete asymptotic expansion is found for the kernel of the inverse operator as the length of the interval tends to infinity.
