Abstract
The problem of finding a solution of the Helmholtz equation in an irregular strip bounded by a line and a curve C: y = y(x) with data specified on C is formulated as an integral of the first kind. The latter is converted in to an equivalent convolution equation which is regularized using Tikhonov method. The error estimates between the regularized solutions and the exact one are given upon the smoothness of the exact one.
