Complex analytic theory of Sturm-Liouville operators with Schatten $p$ -class resolvents

Guglielmo Fucci, Mateusz Piorkowski, Jonathan Stanfill

We use the theory of entire functions of finite order to prove a universal spectral dependence of the blowup/decay rate of solutions of the Sturm-Liouville eigenvalue equation for…

Finer limit circle/limit point classification for Sturm-Liouville operators

Mateusz Piorkowski, Jonathan Stanfill

In this paper we introduce an index $ℓ_{c} \in N_{0} \cup {\infty}$ which we call the `regularization index' associated to the endpoints, $c \in {a, b}$ , of no…

Donoghue $m$ -functions for singular Sturm--Liouville operators

Fritz Gesztesy, Lance L. Littlejohn, Roger Nichols +2

Let $A ˙$ be a densely defined, closed, symmetric operator in the complex, separable Hilbert space $H$ with equal deficiency indices and denote by $\mathcal{N}_i = \ke…
