Abstract

A number of mixed problems of continuum mechanics and mathematical physics are reduced to solving systems of integral equations, whose kernels have singular or logarithmic features. In the case when a layered medium is considered, the kernels of integral equations depend on the difference of arguments. Such systems of integral equations include the Wiener-Hopf equations. The paper develops a method for studying such systems of integral equations, which is based on a method developed for the case of a system consisting of two equations. When studying a number of similar problems for systems of integral equations of finite number, it is sufficient to represent the general form of each component of the solution. A general representation of the solution of such a system of integral equations is given. It can serve the purposes of studying the types of stress concentration at the edges of its research area.

Keywords:

systems of integral equations, meromorphic functions, factorization, general form of solution
