Spectral Properties of a Fourth Order Eigenvalue Problem with Spectral Parameter in the Boundary Conditions

Ziyatkhan Seyfaddin Aliyev, Sevinc Guliyeva


In this paper we consider the eigenvalue problem for fourth order ordinary differ-
ential equation that describes the bending vibrations of a homogeneous rod, in cross-sections of which the longitudinal force acts, the left end of which is xed rigidly and on the right end an inertial mass is concentrated. We characterize the location of the eigenvalues on the real axis, we investigate the structure of root spaces and oscillation properties of eigenfunctions and their derivatives, we study the basis properties in the space $L_p, 1 < p < \infty$, of the system of eigenfunctions of considered problem.
