AB - The problem of solvability of a boundary-value problem for a differential-operator equation of the second order on afinite interval is studied in a complex separable Hilbert space H in the case where the same spectral parameter appearsin the equation in the form of a quadratic function and in the boundary conditions in the form of a linear function and,moreover, the boundary conditions are not separated. The asymptotic behavior of the eigenvalues of one homogeneousabstract boundary-value problem is also investigated. The asymptotic formulas for the eigenvalues are obtained and anapplication of the obtained results to partial differential equations is analyzed.
