The Riemann problem on a three-sheeted surface for which the projections of branching points have one accumulation point
The author deals with a solvability conditions and presents an explicit solution to the Riemann problem on a three-sheeted surface in the case when branching points may be of any order and their projections to the complex plane have a single accumulation point at infinity. In the case of a nonseparating contour \(\Gamma\), the solution to the Riemann problem is expressed in terms of usual integrals of the Cauchy type.
