Numerical and analytical tests of quasi-integrability in modified sine-Gordon models
(SpringerHeidelberg, 2014-01)
Following our attempts to define quasi-integrability in which we related this concept to a particular symmetry of the two-soliton function we check this condition in three classes of modified sine-Gordon models in (1+1) ...
SOME COMMENTS ON QUASI-INTEGRABILITY
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
In this paper we present our preliminary results which suggest that some field theory models are `almost` integrable; i.e. they possess a large number of `almost` conserved quantities. First we demonstrate this, in some ...

The concept of quasi-integrability: a concrete example
(SPRINGER, 2011)
We use the deformed sine-Gordon models recently presented by Bazeia et al [1] to take the first steps towards defining the concept of quasi-integrability. We consider one such definition and use it to calculate an infinite ...
Some properties of (3+1) dimensional vortex solutions in the extended CPN Skyrme-Faddeev model
(Societa Italiana di Fisica - SIFBologna, 2011-12)
We look at properties of vortex solutions of the extended CPN Skyrme-Faddeev model. We show that only holomorphic solutions of the CPN model are also solutions of the Skyrme-Faddeev model. As the total energy of these ...
The concept of quasi-integrability for modified non-linear Schrodinger models
(SPRINGERNEW YORK, 2012)
We consider modifications of the nonlinear Schrodinger model (NLS) to look at the recently introduced concept of quasi-integrability. We show that such models possess an in finite number of quasi-conserved charges which ...
