Soliton resonances for the MKPII
(Springer, 200507)Using the second flow (derivative reactiondiffusion system) and the third one of the dissipative SL(2, ℝ) KaupNewell hierarchy, we show that the product of two functions satisfying those systems is a solution of the ... 
Soliton resonances in a generalized nonlinear Schrödinger equation
(IOP Publishing, 20081114)It is shown that a generalized nonlinear Schrödinger equation proposed by Malomed and Stenflo admits, for a specific range of parameters, resonant soliton interaction. The equation is transformed to the 'resonant' nonlinear ... 
Soliton resonances, black holes and madelung fluid
(World Scientific Publishing, 200102)The reactiondiffusion system realizing a particular gauge fixing condition of the JackiwTeitelboim gravity is represented as a coupled pair of Burgers equations with positive and negative viscosity. For acoustic metric ... 
Solitons of the resonant nonlinear Schrödinger equation with nontrivial boundary conditions: Hirota bilinear method
(Springer, 200707)We use the Hirota bilinear approach to consider physically relevant soliton solutions of the resonant nonlinear Schrödinger equation with nontrivial boundary conditions, recently proposed for describing uniaxial waves in ... 
Some exact and explicit solutions for nonlinear schrödinger equations
(Polish Academy of Sciences Publishing House, 201301)Nonlinear models occur in many areas of applied physical sciences. This paper presents the first integral method to carry out the integration of Schrödingertype equations in terms of traveling wave solutions. Through the ... 
Some exact and explicit solutions to a twocomponent, discrete, nonlinear Schrödinger model
(National Research Council of Canada, 201108)Natural processes and phenomena often display discrete structure. The discrete nonlinear Schrödinger equations are used in both physics and biology to model periodic optical structures and energy transfer in proteins. In ... 
Some exact solutions for Toda type lattice differential equations using the improved (G′/G)expansion method
(Wiley, 201203)Nonlinear lattice differential equations (also known as differentialdifference equations) appear in many applications. They can be thought of as hybrid systems for the inclusion of both discrete and continuous variables. ... 
Some remarks on expfunction method and its applications
(IOP Publishing, 201109)Recently, many important nonlinear partial differential equations arising in the applied physical and mathematical sciences have been tackled by a popular approach, the socalled Expfunction method. In this paper, we ... 
Some remarks on Expfunction method and its applications  A supplement
(IOP Publishing, 201311)Recently, the authors of [Commun. Theor. Phys. 56 (2011) 397] made a number of useful observations on Expfunction method. In this study, we focus on another vital issue, namely, the misleading results of double Expfunction ... 
Special precovers in cotorsion theories
(Cambridge University Press, 200206)A cotorsion theory is defined as a pair of classes Extorthogonal to each other. We give a hereditary condition (HC) which is satisfied by the (flat, cotorsion) cotorsion theory and give properties satisfied by arbitrary ... 
A Stabilizing subgrid for convectiondiffusion problem
(World Scientific Publishing, 200602)A stabilizing subgrid which consists of a single additional node in each triangular element is analyzed by solving the convectiondiffusion problem, especially in the case of small diffusion. The choice of the location of ... 
Strang splitting method for BurgersHuxley equation
(Elsevier, 20160305)We derive an analytical approach to the Strang splitting method for the BurgersHuxley equation (BHE) ut+αuuxε uXX=β(1u)(uγ)u. We proved that Srtang splitting method has a second order convergence in Hs(R), where Hs(R) ... 
Strongly noncosingular modules
(Iranian Mathematical Society, 201608)An Rmodule M is called strongly noncosingular if it has no nonzero Radsmall (cosingular) homomorphic image in the sense of Harada. It is proven that (1) an Rmodule M is strongly noncosingular if and only if M is coatomic ... 
Strongly radical supplemented modules
(Springer, 201201)Zöschinger studied modules whose radicals have supplements and called these modules radical supplemented. Motivated by this, we call a module strongly radical supplemented (briefly srs) if every submodule containing the ... 
Strongly secure authenticated key exchange without NAXOS' approach
(Springer, 2009)LaMacchia, Lauter and Mityagin [15] proposed the extended CanettiKrawczyk (eCK) model and an AKE protocol, called NAXOS. Unlike previous security models, the adversary in the eCK model is allowed to obtain ephemeral secret ...
