Essential self-adjointness of even-order, strongly singular, homogeneous half-line differential operators
Fritz Gesztesy, Markus Hunziker, Gerald Teschl
We consider essential self-adjointness on the space of even order, strongly singular, homogeneous differential operators associated with differential exp…

A Bessel Analog of the Riesz Composition Formula
Christoph Fischbacher, Fritz Gesztesy, Roger Nichols
We provide an elementary derivation of the Bessel analog of the celebrated Riesz composition formula and use the former to effortlessly derive the latter.

The Jacobi operator on and its various -functions
Fritz Gesztesy, Lance L. Littlejohn, Mateusz Piorkowski +1
We offer a detailed treatment of spectral and Weyl-Titchmarsh-Kodaira theory for all self-adjoint Jacobi operator realizations of the differential expression \begin{align*} τ_{α,β}…
