The equation of convolution on a large finite interval with the symbol which has zeros of nonintegral powers
A. M. Budylin, S. B. Levin St. Petersburg State University, St. Petersburg, Russia
Abstract:
We study one equation of convolution on a large finite interval. This equation arose in acoustics for a description of a wave conductor surface with a bed of ice. The main feature of this equation is that the symbol of the corresponding operator has zeros of nonintegral degrees on the dual variable so that the inverse operator is a long-range one. We found power-order complete asymptotic expansion for a kernel of the inverse operator as a length of the interval tends to infinity.
Key words and phrases:
semiclassical asymptotics, singular integral equations, Wiener-Hopf method, Schwartz alternating method.
