Abstract

The paper considers a problem with the Frankl condition on different parts of
the cut edges along a segment of the degeneracy line for a mixed-type equation with a singular
coefficient. The problem is investigated TF in the case / 2 1 0 -m < b < of , uniqueness of the
solution of the problem TF and the existence of a solution TF to the singular Tricomi integral
equation is proved.
