Zeros of orthogonal polynomials and some matrix inequalities
Carmen Escribano, Raquel Gonzalo
The main aim of this work is to apply the matrix approach of ortho\-gonal polynomials associated with infinite Hermitian definite positive matrices in relation with an important qu…
Boundedness of zeros of Sobolev orthogonal polynomials via generalized eigenvalues
C. Escribano, R. Gonzalo
The main aim of this work is to apply the study of the asymptotic behaviour of generalized eigenvalues between infinite Hermitian definite positive matrices in an important questio…
Smallest and largest generalized eigenvalues of large moment matrices and some applications
C. Escribano, R. Gonzalo, E. Torrano
The main aim of this work is to compare two Borel measures thorough their moment matrices using a new notion of smallest and largest generalized eigenvalues. With this approach we…
A Characterization of Polynomial Density on Curves via Matrix Algebra
Carmen Escribano, Raquel Gonzalo, Emilio Torrano
In this work, our aim is to obtain conditions to assure polynomial approximation in Hilbert spaces , with a compactly supported measure in the complex plane, in terms…
Asymptotic Smoothness, Convex Envelopes and Polynomial Norms
Jesús A. Jaramillo, Raquel Gonzalo, Diego Yáñez
We introduce a suitable notion of asymptotic smoothness on infinite dimensional Banach spaces, and we prove that, under some structural restrictions on the space, the convex envelo…
Inverses of moment Hermitian matrices
C. Escribano, R. Gonzalo, E. Torrano
Motivated by [9] we study the existence of the inverse of infinite Hermitian moment matrices associated with measures with support on the complex plane. We relate this problem to t…
