On a Statement of the Boundary Value Problem for a Generalized Cauchy-Riemann Equation with Nonisolated Singularities in a Lower-Order Coefficient

The paper studies how the statement of boundary value problems for a generalized Cauchy-Riemann equation is affected by nonisolated singularities in a lower-order coefficient of the equation assuming that these singularities are pairwise disjoint and do not pass through the origin. It turns out that posing only a condition on the boundary of the domain is insufficient in such problems. Therefore, we consider a case combining elements of the Riemann-Hilbert problem on the boundary of the domain and a linear transmission problem on the circles supporting the singularities in the lower-order coefficient inside the domain.
