AB - <p>In the present work found the root of the positive operator of the Sturm - Liouville problem of the<br>fourth order, which is invertible composition operator of the Sturm - Liouville problem and its adjoint. The found<br>root does not possess the property of positivity, but is a self-adjoint operator in the essential. One theorem of Putnam<br>of algebraic character is used as a leading idea. It is hoped that the results will find applications in spectral operator<br>theory and theoretical physics.</p>
