Symmetrization process and truncated orthogonal polynomials
Diego Dominici, Juan C. García-Ardila, Francisco Marcellán
We define the family of truncated Laguerre polynomials , orthogonal with respect to the linear functional defined by $$\langle{\ell,p\rangle}=\int_{0}^zp(x)x^αe^{-…

Linear functionals and - coherent pairs of the second kind
Diego Dominici, Francisco Marcellán
We classify all the \emph{-}coherent pairs of measures of the second kind on the real line. We obtain cases, corresponding to all the families of discrete semiclassical orth…
