On the solvability of boundary-value problems for third-order equations of parabolic-hyperbolic type with lower terms

In this paper, boundary-value problems for a third-order mixed differential equation of the parabolic-hyperbolic type with a fractional Gerasimov–Caputo operator are examined. Classes of functions that ensure the unique solvability of the boundary-value problem are found. The existence and uniqueness of a solution of the boundary-value problem are proved.
