Query: On the Riemann-Hilbert problem for analytic functions in circular
  domains   It is proved the existence of single-valued analytic solutions in the unit
disk and multivalent analytic solutions in domains bounded by a finite
collection of circles for the Riemann-Hilbert problem with coefficients of
sigma-finite variation and with boundary data that are measurable with respect
to logarithmic capacity. It is shown that these spaces of solutions have the
infinite dimension.
