A practical method for recovering Sturm-Liouville problems from the Weyl function

Vladislav V. Kravchenko, Sergii M. Torba

In the paper we propose a direct method for recovering the Sturm-Liouville potential from the Weyl-Titchmarsh -function given on a countable set of points. We show that using th…
