We obtain some conclusions about multiplicity of the eigenvalues based on the estimation of solutions. Asymptotic formules of eigenfunctions in each interval are obtained. Also, properties related to the characteristic function of the problem are given and proven. We prove that, under certain conditions on potential matrix, the problem can only have a finite number of eigenvalues with multiplicity m.}, number={2}, publisher={Ağrı İbrahim Çeçen University}
