On the asymptotic normality of the Legendre-Stirling numbers of the second kind
Wolfgang Gawronski, Lance L. Littlejohn, Thorsten Neuschel
For the Legendre-Stirling numbers of the second kind asymptotic formulae are derived in terms of a local central limit theorem. Thereby, supplements of the recently published asymp…
A Spectral Study of the Second-Order Exceptional -Jacobi Differential Expression and a Related Non-classical Jacobi Differential Expression
Constanze Liaw, Lance L. Littlejohn, Jessica Stewart +1
The exceptional -Jacobi differential expression is a second-order ordinary differential expression with rational coefficients; it was discovered by Gómez-Ullate, Kamran and…
Classical and Sobolev Orthogonality of the Nonclassical Jacobi Polynomials with Parameters α=β=-1
Andrea Bruder, Lance Littlejohn
In this paper, we consider the second-order differential expression \ell [y](x)=(1-x^2)(-(y'(x))'+k(1-x^2)^(-1)y(x))(x\in(-1,1)). This is the Jacobi differential expression with no…
