Characterization of Logarithmic Fekete Critical Configurations of at Most Six Points in All Dimensions
Diego Armentano, Leandro Bentancur, Federico Carrasco +3
We consider the logarithmic Fekete problem, which consists of placing a fixed number of points on the unit sphere in , in such a way that the product of all pairs of…

On the logarithmic energy of solutions to the polynomial eigenvalue problem
Diego Armentano, Federico Carrasco, Marcelo Fiori
In this paper, we compute the expected logarithmic energy of solutions to the polynomial eigenvalue problem for random matrices. We generalize some known results for the Shub-Smale…

High Order Numerical Methods To Approximate The Singular Value Decomposition
Diego Armentano, Jean-Claude Yakoubsohn
In this paper, we present a class of high order methods to approximate the singular value decomposition of a given complex matrix (SVD). To the best of our knowledge, only methods…
