Characterization theorem for Laguerre-Hahn orthogonal polynomials on non-uniform lattices
Amílcar Branquinho, Maria das Neves Rebocho
It is stated and proved a characterization theorem for Laguerre-Hahn orthogonal polynomials on non-uniform lattices. This theorem proves the equivalence between the Riccati equatio…
