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…
Quantum Technologies in the Telecommunications Industry
Vicente Martin, Juan Pedro Brito, Carmen Escribano +13
Quantum based technologies have been fundamental in our world. After producing the laser and the transistor, the devices that have shaped our modern information society, the possib…
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…
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…
The Hessenberg matrix and the Riemann mapping
Carmen Escribano, Antonio Giraldo, M. Asunción Sastre +1
We consider a Jordan arc Γin the complex plane \mathbb{C} and a regular measure μwhose support is Γ. We denote by D the upper Hessenberg matrix of the multiplication by z operator…
