Integral representation of solutions and Riemann–Hilbert type problem for the Cauchy–Riemann equation with strong singularity in the lower order coefficient in a domain with piecewise smooth boundary

The goal of this work is to construct the general solution of the Cauchy–Riemann equation with strong singularities in the lower order coefficient and to study the Riemann–Hilbert boundary value problem in a domain with a piecewise smooth boundary.
