Orthogonal polynomials associated with an inverse quadratic spectral transform

M. Alfaro, F. Marcellan, A. Pena +1

Let ${P_{n}}_{n \geq 0}$ be a sequence of monic orthogonal polynomials with respect to a quasi--definite linear functional $u$ and ${Q_{n}}_{n \geq 0}$ a sequence of polynomials define…

Asymptotics for a generalization of Hermite polynomials

M. Alfaro, J. J. Moreno-Balcazar, A. Pena +1

We consider a generalization of the classical Hermite polynomials by the addition of terms involving derivatives in the inner product. This type of generalization has been studied…

When do linear combinations of orthogonal polynomials yield new sequences of orthogonal polynomials?

M. Alfaro, F. Marcellan, A. Pena +1

Given ${P_{n}}$ a sequence of monic orthogonal polynomials, we analyze their linear combinations ${Q_{n}}$ with constant coefficients and fixed length $k + 1$ . Necessary and suffici…

Sobolev orthogonal polynomials: balance and asymptotics

M. Alfaro, J. J. Moreno-Balcazar, A. Pena +1

Let $μ_{0}$ and $μ_{1}$ be measures supported on an unbounded interval and $S_{n, λ_{n}}$ the extremal varying Sobolev polynomial which minimizes \begin{equation*} < P, P >_{λ_n}=\int P^2…
