Symmetric operators with real defect subspaces of the maximal dimension. Applications to differential operators

Vadim Mogilevskii

Let $\gH$ be a Hilbert space and let $A$ be a simple symmetric operator in $\gH$ with equal deficiency indices $d := n_{\pm} (A) < \infty$ . We show that if, for all $ł$ in an open interva…

Minimal spectral functions of an ordinary differential operator

Vadim Mogilevskii

Let $l [y]$ be a formally selfadjoint differential expression of an even order on the interval $[0, b > (b \leq \infty)$ and let $L_{0}$ be the corresponding minimal operator. By using…
