We study a question of unique solvability of a boundary-value problem with fractional derivatives for a mixed-type equation of the second order. The uniqueness theorem is proved by using restrictions on known functions. The existence of a solution to the problem is proved by reduction to the Fredholm equation of the second kind. Unconditional solvability of this equation follows from the uniqueness of a solution.
Keywords: operator of fractional differentiation, Gauss hypergeometric function, Cauchy problem, Fredholm integral equation.
