An analytical method of solution of integral, integrodifferential equations
and their systems of special forms, is described here. The method consists
of reducing the mentioned equations to Riemann's problem of the theory of
analytic functions for a vector of the second or more order and its effecti
ve solution by reducing them to infinite algebraic systems with exponential
rate of convergence of the approximate solution to the coexact one. Soluti
ons of some problems of the theory of cracks in composite bodies carried ou
t with the help of this method are also given.
