Abstract | Systems-conjugate points have been introduced and studied by John Barrett [3] in relation with the self-adjoint fourth order differential equation (r(x)y ′′) ′′ − (q(x)y ′ ) ′ = p(x)y, where r(x) > 0, p(x) > 0 and q ≡ 0. In this paper we extend some of his results to more general cases, when q(x) is free of any sign restrictions. |
