This paper presents results on the correctness (uniqueness and non-uniqueness, existence and non-existence of solutions) of non-local boundary value problems with partially integral conditions with respect to the time variable for fourth-order quasi-hyperbolic differential equations. The influence of the spectral parameter and the behavior of the integrand on the solvability of the non-local problem are also determined.
