Modified AKNS model, Riccati-type pseudo-potential approach and infinite towers of quasi-conservation laws
Autor: Blas, H., Maguiña, M. Cerna, Santos, L. F. dos
Publikováno v: Int. J. Mod. Phys. B36 (2022) 2250070
A dual Riccati-type pseudo-potential formulation is introduced for a modified AKNS system (MAKNS) and infinite towers of novel anomalous conservation laws are uncovered. In addition, infinite towers of exact non-local conservation laws are uncovered

Modified non-linear Schr\'odinger models, ${\cal C}{\cal P}_s{\cal T}_d$ symmetry, dark solitons and infinite towers of anomalous charges
Autor: Blas, H., Maguiña, M. Cerna, Santos, L. F. dos
Some modified (defocusing) non-linear Schr\"odinger models (MNLS) possess infinite towers of anomalous conservation laws with asymptotically conserved charges. The so-called anomalies of the quasi-conservation laws vanish upon space-time integration

Modified non-linear Schr\'odinger models, ${\cal C}{\cal P}_s{\cal T}_d$ invariant $N-$bright solitons and infinite towers of anomalous charges
Autor: Blas, H., Maguiña, M. Cerna, Santos, L. F. dos
Modifications of the non-linear Schr\"odinger model (MNLS) $ i \partial_{t} \psi(x,t) + \partial^2_{x} \psi(x,t) - [\frac{\delta V}{\delta |\psi|^2} ] \psi(x,t) = 0,$ where $\psi \in C$ and $V: R_{+} \rightarrow R$, are considered. We show that the M

Nonvanishing boundary conditions and dark solitons in the NLS model
Autor: Santos, L. F. dos, Blas, H., da Silva, M. J. B. F.
Publikováno v: PoS ISFTG:043,2009
We consider non-vanishing boundary conditions (NVBC) for the NLS model [6,7,27] in the context of the hybrid dressing transformation and $\tau$-function approach. In order to write the NLS model in a suitable form to deal with non-vanishing boundary

The increasing use of natural biodegradable polymers to preserve foods is a consequence of the concern of society with sustainability. Starch stands out amongst the natural polymers due to its great availability on a worldwide scale, high extraction
