In this article we introduce some matrix manipulations that allow us to obtain a version of the original Christoffel-Darboux formula, which is of interest in many applications of linear algebra. Using these developments matrix and Jensen’s inequality, we obtain the main result of this proposal, which is the generalization of the maximum entropy theorem of Burg for multivariate processes.
Keywords: multivariate processes; maximum entropy theorem; Christoffel-Darboux formula
En este artículo se introducen algunas manipulaciones matriciales que nos permiten obtener una versión de la fórmula original de ChristoffelDarboux, la cual resulta de interés en muchas aplicaciones del álgebra lineal. Usando estos desarrollos matriciales y la desigualdad de Jensen, se obtiene el resultado principal de esta propuesta, que consiste en la generalización del teorema de entropía máxima de Burg para procesos multivariados.
Palabras clave: procesos multivariados; teorema de entropía máxima; fórmula de Christoffel-Darboux
