Super-Hamiltonian Structures and Conservation Laws of a New Six-Component Super-Ablowitz-Kaup-Newell-Segur Hierarchy

open access: yesAbstract and Applied Analysis, 2014
A six-component super-Ablowitz-Kaup-Newell-Segur (-AKNS) hierarchy is proposed by the zero curvature equation associated with Lie superalgebras.

A novel analytical method for solving (2+1)- dimensional extended Calogero-Bogoyavlenskii-Schiff equation in plasma physics

open access: yesJournal of Ocean Engineering and Science, 2021
In this paper, the new travelling wave solutions of the (2+1)-dimensional extended Calogero-Bogoyavlenskii-Schiff (ECBS) equation are investigated. The main aim of this work is to find the new exact solutions with the aid of relatively new (G′G′+G+A ...

Impact of reserve area on reproduction of a moth‐pollinated Stackhousia Sm. (Celastraceae) species in a fragmented landscape

open access: yesAustral Ecology, Volume 48, Issue 8, Page 2053-2075, December 2023., 2023
Abstract Landscape disturbance frequently results in reduced pollination and reproduction of animal‐pollinated plants. However, few studies globally, and no studies in Australia, have focused on the impact(s) on plants with nocturnal moth pollinators.

Cole-Hopf Like Transformation for Schr\"odinger Equations Containing Complex Nonlinearities [PDF]

open access: yes, 2002
We consider systems, which conserve the particle number and are described by Schr\"odinger equations containing complex nonlinearities. In the case of canonical systems, we study their main symmetries and conservation laws.

Gardner's deformation of the Krasil'shchik-Kersten system [PDF]

open access: yes, 2015
The classical problem of construction of Gardner's deformations for infinite-dimensional completely integrable systems of evolutionary partial differential equations (PDE) amounts essentially to finding the recurrence relations between the integrals of ...

Comment on "Soliton ratchets induced by excitation of internal modes" [PDF]

open access: yes, 2004
Very recently Willis et al. [Phys. Rev. E {\bf 69}, 056612 (2004)] have used a collective variable theory to explain the appearance of a nonzero energy current in an ac driven, damped sine-Gordon equation.

Duality relation among the Hamiltonian structures of a parametric coupled Korteweg-de Vries system

open access: yesOpen Physics, 2016
We obtain the full Hamiltonian structure for a parametric coupled KdV system. The coupled system arises from four different real basic lagrangians. The associated Hamiltonian functionals and the corresponding Poisson structures follow from the geometry ...

Analysis of time-fractional hunter-saxton equation: a model of neumatic liquid crystal

open access: yesOpen Physics, 2016
In this work, a theoretical study of diffusion of neumatic liquid crystals was done using the concept of fractional order derivative. This version of fractional derivative is very easy to handle and obey to almost all the properties satisfied by the ...

New analytical solutions for conformable fractional PDEs arising in mathematical physics by exp-function method

open access: yesOpen Physics, 2017
Modelling of physical systems mathematically, produces nonlinear evolution equations. Most of the physical systems in nature are intrinsically nonlinear, therefore modelling such systems mathematically leads us to nonlinear evolution equations.
