Asymptotic Expansions of Feynman Amplitudes in a Generic Covariant Gauge
C. A. Linhares, A. P. C. Malbouisson, I. Roditi
We show in this paper how to construct Symanzik polynomials and the Schwinger parametric representation of Feynman amplitudes for gauge theories in an unspecified covariant gauge.…
Improving the Global Fitting Method on Non-Linear Time Series Analysis
L. M. C. R. Barbosa, L. G. S. Duarte, C. A. Linhares +1
In this paper, we are concerned with improving the forecast capabilities of the Global approach to Time Series. We assume that the normal techniques of Global mapping are applied,…
First-order phase transitions in superconducting films: A Euclidean model
C. A. Linhares, A. P. C. Malbouisson, Y. W. Milla +1
In the context of the Ginzburg--Landau theory for critical phenomena, we consider the Euclidean model bounded by two parallel planes, a distance separating them. Th…
