Problem with Nonlocal Conditions, Specified on Parts of the Boundary Characteristics and on the Degeneracy Segment, for the Gellerstedt Equation with Singular Coefficient

For the Gellerstedt equation with a singular coefficient, we investigate a boundary value problem with nonlocal conditions, given on parts of the boundary characteristics, and a Frankl type condition, specified on the degeneracy segment. We prove the uniqueness and existence theorems.
