For the Gellerstedt equation with a singular coefficient in some mixed domain, when the ellipticity boundary coincides with the segment of the Oy axis and the normal curve of the equation, the problem with the Bitsadze–Samarskii conditions on the elliptic boundary and on the degeneration line is studied. The correctness of the formulated problem is proved.
