On the families of orthogonal polynomials associated to the Razavy potential

Federico Finkel, Artemio Gonzalez-Lopez, Miguel A. Rodriguez

We show that there are two different families of (weakly) orthogonal polynomials associated to the quasi-exactly solvable Razavy potential $V(x)=(\z \cosh 2x-M)^2$ ($\z>0$, $M\in\m…
