QBD processes associated with Jacobi-Koornwinder bivariate polynomials and urn models
Lidia Fernández, Manuel D. de la Iglesia
We study a family of quasi-birth-and-death (QBD) processes associated with the so-called first family of Jacobi-Koornwinder bivariate polynomials. These polynomials are orthogonal…
Sobolev orthogonal polynomials on the conic surface
Lidia Fernandez, Teresa Perez, Miguel Pinar +1
Orthogonal polynomials with respect to the weight function , , on the conic surface are st…
On Gegenbauer Point Processes on the unit interval
Carlos Beltrán, Antonia M. Delgado, Lidia Fernández +1
In this note we compute the logarithmic energy of points in the unit interval chosen from different Gegenbauer Determinantal Point Processes. We check that all the differe…
Sobolev orthogonal polynomials on product domains
L. Fernández, F. Marcellán, T. E. Pérez +2
Orthogonal polynomials on the product domain with respect to the inner product $$ \langle f,g \rangle_S = \int_{a_1}^{b_1} \int_{a_2}^{b_2} \nabla f(x,…
Orthogonal polynomials in several variables for measures with mass points
A. M. Delgado, L. Fernandez, T. E. Perez +2
Let be a measure in obtained from adding a set of mass points to another measure . Orthogonal polynomials in several variables associated with can be e…
Krall--type Orthogonal Polynomials in several variables
Lidia Fernandez, Teresa E. Perez, Miguel A. Pinar +1
For a bilinear form obtained by adding a Dirac mass to a positive definite moment functional in several variables, explicit formulas of orthogonal polynomials are derived from the…
