Chebyshev approximation of exponential data
Mariano Rodríguez-Arias Fernández, Javier Cabello Sánchez, Juan Antonio Fernández Torvisco
In this paper we present an algorithm to fit data via exponentials when the error is measured using the max-norm. We prove the necesssary results to show that the algorithm will co…
On the contribution of different coupling constants in the infrared regime of Yang-Mills theory: a Curci-Ferrari approach
Matías Fernández, Marcela Peláez
We investigate the influence of the different vertices of two-point correlation functions in the infrared regime of Yang-Mills theory using a phenomenological description. This reg…
A New Algorithm to Fit Exponential Decays
Juan Antonio Fernández Torvisco, Mariano Rodríguez-Arias Fernández, Javier Cabello Sánchez
This paper deals with some nonlinear problems which exponential and biexponential decays are involved in. A proof of the quasiconvexity of the error function in some of these probl…
