On the "movement" of the zeros of eigenfunctions of the Sturm-Liouville problem

Tigran Harutyunyan, Avetik Pahlevanyan, Yuri Ashrafyan

We study the dependence of the zeros of eigenfunctions of Sturm-Liouville problem on the parameters that define the boundary conditions. As a corollary, we obtain Sturm oscillation…

Riesz bases generated by the spectra of Sturm-Liouville problems

Tigran Harutyunyan, Avetik Pahlevanyan, Anna Srapionyan

Let ${λ_{n}^{2}}_{n = 0}^{\infty}$ be the spectra of a Sturm-Liouville problem on $[0, π]$ . We investigate the question: Do the systems ${cos (λ_{n} x)}_{n = 0}^{\infty}$ or $\{\sin(λ_n x)…
