Riemann problem on ultrahyperelliptic surface
The author considers the Riemann boundary value problem in the case of a non-compact Riemann surface. This problem is solved for an arbitrary piece-smooth curve \(\Gamma\) lying on an ultrahyperelliptic surface in the space of Hölder functions on \(\Gamma,\) except, may be, knots.
