Abstract

Riemann-Hilbert and Poincaré type problems are studied for the Bitsadze equation with additional minor terms consisting of first-order partial derivatives and with coefficients containing a supersingular point. It is shown that with certain constraints on the minor term coefficients, the Bitsadze equation and the Riemann-Hilbert type problem are reduced to the equivalent Poincaré problem. Matters concerned with the solution uniqueness of the problems under consideration and their explicit representation are addressed.
