An internal boundary value problem with the Riemann-Liouville operator for the mixed type equation of the third order

Abstract

The unique solvability of the internal boundary value problem is investigated for the mixed type equation of the third order with Riemann-Liouville operators in boundary condition. The uniqueness theorem is proved for the different orders of operators of fractional integro-differentiation when the inequality constraints on the known functions exist. The existence of solution is verified by the method of reduction to Fredholm equations of the second kind, which unconditional solvability follows from the uniqueness of the solution of the problem.
