Self-Dual Skyrmions on the Spheres
Y. Amari, L. A. Ferreira
We construct self-dual sectors for scalar field theories on a -dimensional Minkowski space-time with target space being the -dimensional sphere . The constr…
Quasi-integrability of deformations of the KdV equation
F. ter Braak, L. A. Ferreira, W. J. Zakrzewski
We investigate the quasi-integrability properties of various deformations of the Korteweg-de Vries (KdV) equation, depending on two parameters and ,…
A mild source for the Wu-Yang magnetic monopole
C. P. Constantinidis, L. A. Ferreira, G. Luchini
We establish that the Wu-Yang monopole needs the introduction of a magnetic point source at the origin in order for it to be a solution of the differential and integral equations f…
Quasi-integrable deformations of the Affine Toda Theory
Luiz A. Ferreira, Pawel Klimas, Wojtek J. Zakrzewski
We consider deformations of the Affine Toda theory (AT) and investigate the integrability properties of the deformed theories. We find that for some special deformations al…
A remark on the asymptotic form of BPS multi-dyon solutions and their conserved charges
C. P. Constantinidis, L. A. Ferreira, G. Luchini
We evaluate the gauge invariant, dynamically conserved charges, recently obtained from the integral form of the Yang-Mills equations, for the BPS multi-dyon solutions of a Yang-Mil…
Quasi-Integrable Deformations of the Bullough-Dodd model
Vinicius H. Aurichio, L. A. Ferreira
It has been shown recently that deformations of some integrable field theories in (1+1)-dimensions possess an infinite number of charges that are asymptotically conserved in the sc…
