We consider questions of solvability and constructing the solution to a nonlocal mixed boundary value problem for a homogeneous mixed type fourth-order differential equation. We use the spectral method based on separation of variables. A criterion for unique solvability of the problem is obtained. We also study questions of existence of solutions in the case where uniqueness of the solution does not hold.
Keywords: boundary value problem, mixed type differential equation, fourth-order equation, integral conditions, unique solvability.
