Disconjugacy, regularity of multi-indexed rationally-extended potentials, and Laguerre exceptional polynomials
Yves Grandati, Christiane Quesne
The power of the disconjugacy properties of second-order differential equations of Schrödinger type to check the regularity of rationally-extended quantum potentials connected with…

A short proof of the Gaillard-Matveev theorem based on shape invariance arguments
Yves Grandati
We propose a simple alternative proof of the Wronskian representation formula obtained by Gaillard and Matveev for the Darboux-Pöschl-Teller (DPT) potentials. It rests on the use o…

New rational extensions of solvable potentials with finite bound state spectrum
Yves Grandati
Using the disconjugacy properties of the Schrödinger equation, it is possible to develop a new type of generalized SUSY QM partnership which allows to generate new solvable rationa…
