In this work, we construct a general solution of the generalized Cauchy-–Riemann equation whose coefficient admits a first-order singularity on a circle contained in the domain, and study a boundary-value problem that combines elements of the Riemann-–Hilbert problem and the linear conjugation problem.
Mots-clés : Cauchy–Riemann equations
Keywords: singularity in the coefficient, Pompeiu–Vekua operator, boundary-value problem
