Exceptional Hahn and Jacobi polynomials with an arbitrary number of continuous parameters
(Wiley, 2021-09-30)We construct new examples of exceptional Hahn and Jacobi polynomials. Exceptional polynomials are orthogonal polynomials ...

Modifications of quasi-definite linear functionals via addition of delta and derivatives of delta Dirac functions
(Elsevier, 2004)We consider the general theory of the modifications of quasi-definite linear functionals by adding discrete measures. We ...

On some tridiagonal k-Toeplitz matrices: algebraic and analytical aspects. Applications
(Elsevier, 2005-12-15)In this paper we use the analytic theory for 2 and 3-Toeplitz matrices to obtain the explicit expressions for the eigenvalues, ...

On the Krall-type discrete polynomials
(Elsevier, 2004-07-01)In this paper we present a unified theory for studying the so called Kralltype discrete orthogonal polynomials. In ...

q-Classical polynomials and the q-Askey and Nikiforov-Uvarov tableaus
(Elsevier, 2001-10-15)In this paper we continue the study of the q-classical (discrete) polynomials (in the Hahn's sense) started in Medem et ...

Second order difference equations for certain families of discrete polynomials
(Elsevier, 1998-11-16)In this paper we will consider two algorithms which allow us to obtain second order linear di erence equations for certain ...

Spectral properties of certain tridiagonal matrices
(Elsevier, 2012-02-01)We study spectral properties of irreducible tridiagonal k−Toeplitz matrices and certain matrices which arise as perturbations of them.
