Asymptotic for orthogonal polynomials with respect to a rational modification of a measure supported on the semi-axis

C. Féliz-Sánchez, H. Pijeira-Cabrera, J. Quintero-Roba

Given a sequence of orthogonal polynomials ${L_{n}}_{n = 0}^{\infty}$ , orthogonal with respect to a positive Borel $ν$ measure supported on $R_{+}$ , let ${Q_{n}}_{n = 0}^{\infty}$ b…

Iterated integrals and Borwein-Chen-Dilcher polynomials

Manuel Bello-Hernández, Héctor Pijeira-Cabrera, Daniel Rivero-Castillo

We study the zero location and the asymptotic behavior of iterated integrals of polynomials. Borwein-Chen-Dilcher's polynomials play an important role in this issue. For these poly…

Discrete-Continuous Jacobi-Sobolev Spaces and Fourier Series

Abel Díaz-González, Francisco Marcellán-Español, Héctor Pijeira-Cabrera +1

Let $p \geq 1$ , $\ell\in \NN$, $α, β > - 1$ and $\varpi=(ω_0,ω_1, \dots, ω_{\ell-1})\in \RR^{\ell}$. Given a suitable function $f$ , we define the discrete-continuous Jacobi-Sobolev norm…
