A constructive solution to the Riemann–Hilbert boundary value problem as well as to the C-linear conjugation problem (or Riemann problem) with a special piecewise constant matrix for a multiply connected domain is obtained. The result is based on a vector generalization of the scalar method of functional equations in complex domain and on application of the Christoffel–Schwarz transformation of the half-plane onto a circular polygon.

Keywords: Riemann–Hilbert boundary value problem, vector-matrix, C-linear conjugation problem, multiply connected domain, Christoffel–Schwarz transformation, functional equation
