A mathematical basis for the graphene
(2020)
We present a new basis of representation for the graphene honeycomb structure that facilitates the solution of the eigenvalue problem by reducing it to one dimension. We define spaces in these geometrical basis that allow ...
On the graphene Hamiltonian operator
(2020)
We solve a second-order elliptic equation with quasi-periodic boundary conditions defined on a honeycomb lattice that represents the arrangement of carbon atoms in graphene. Our results generalize those found by Kuchment ...
Self-similarity and asymptotic stability for coupled nonlinear Schrodinger equations in high dimensions
(Elsevier Science BvAmsterdamHolanda, 2012)
Precision of yule-walker methods for the arma spectral model
(2004-12-01)
In this work a new method is proposed of separated estimation for the ARMA spectral model based on the modified Yule-Walker equations and on the least squares method. The proposal of the new method consists of performing ...
Métodos variacionais e a estabilidade de ondas viajantes periódicas para equações do tipo Korteweg de-Vries e Benjamin-Bona-Mahony
(Programa de Pós-Graduação em MatemáticaCentro de Ciências Exatas, 2021)
Higher-order spectral analysis and weak asymptotic stability of convex processes
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-06-01)
This paper deals with the asymptotic stability analysis of a discrete dynamical inclusion whose right-hand side is a convex process. We provide necessary and sufficient conditions for weak asymptotic stability, and obtain ...
On the graphene Hamiltonian operator
(Springer, 2020)
We solve a second-order elliptic equation with quasi-periodic boundary conditions defined on a honeycomb lattice that represents the arrangement of carbon atoms in graphene. Our results generalize those found by Kuchment ...
A Comparison of Segmentation Procedures and Analysis of the Evolution of Spectral Parameters
