The spectral -function of Sturm--Liouville operators with generalized point potentials
Guglielmo Fucci, Jonathan Stanfill
This work analyzes the spectral zeta function associated with regular and singular Sturm--Liouville operators endowed with generalized point potentials. The point interactions…

Complex analytic theory of Sturm-Liouville operators with Schatten -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…
