Considerations on the concepts of nature, space, and morphology in Alexander von Humboldt and on the genesis of modern physical geography
(Fundaco Oswaldo CruzRio De Janeiro, RjBrasil, 2010)
The Clifford Algebra Of Physical Space And Dirac Theory

The Schrodinger and Pauli-Dirac Oscillators in Noncommutative Phase Space
(Springer/plenum Publishers, 2011-02-01)
We investigate the non-relativistic Schrodinger and Pauli-Dirac oscillators in noncommutative phase space using the five-dimensional Galilean covariant framework. The Schrodinger oscillator presented the correct energy ...
Neutrino oscillation in Weitzenbock space-time
(2000-09-10)
In the framework of the teleparallel equivalent of general relativity, we obtain the evolution equation of the neutrino oscillation in vacuum. A comparison with the equivalent result of general relativity case, shows that ...
Integrable theories and loop spaces: fundamentals, applications and new developments
(World Scientific PublishingSingapore, 2009)
We review our proposal to generalize the standard two-dimensional flatness construction
of Lax–Zakharov–Shabat to relativistic field theories in d + 1 dimensions. The fundamentals
from the theory of connections on loop ...

Discrete squeezed states for finite-dimensional spaces
(2007-09-05)
We show how discrete squeezed states in an N2 -dimensional phase space can be properly constructed out of the finite-dimensional context. Such discrete extensions are then applied to the framework of quantum tomography and ...
A model for Hopfions on the space-time S(3)xR
(American Institute of Physics (AIP), 2005-01-01)
We construct static and time dependent exact soliton solutions for a theory of scalar fields taking values on a wide class of two dimensional target spaces, and defined on the four dimensional space-time S-3 X R. The ...
Wide localized solitons in systems with time- and space-modulated nonlinearities
(2012-08-23)
In this work we apply point canonical transformations to solve some classes of nonautonomous, nonlinear Schrödinger equations, namely, those which possess specific cubic and quintic (time- and space-dependent) nonlinearities. ...
