Qısa məlumat

In this paper, we investigate the boundary value problem for fourth order differential operator equations with unbounded operator coefficients and one lambda-dependent boundary condition. We obtain an asymptotic formula for eigenvalues and a trace formula for the corresponding self-adjoint operator.
