Analytic solutions to nonlinear differentialdifference equations by means of the extended (G′/G)expansion method
(IOP Publishing, 201010)In this paper, a discrete extension of the (G′/G)expansion method is applied to a relativistic Toda lattice system and a discrete nonlinear Schrödinger equation in order to obtain discrete traveling wave solutions. Closed ... 
Boundary shape and Casimir energy
(IOP Publishing, 200908)Casimir energy changes are investigated for geometries obtained by small but arbitrary deformations of a given geometry for which the vacuum energy is already known for the massless scalar field. As a specific case, ... 
The Cauchy problem for the planar spinliquid model
(IOP Publishing, 2005)In this paper, we study the Cauchy problem of a twodimensional model for a moving ferromagnetic continuum and prove global existence and uniqueness of solutions. In addition, equivalence to the coupled system of nonlinear ... 
Damped parametric oscillator and exactly solvable complex Burgers equations
(IOP Publishing, 2012)We obtain exact solutions of a parametric Madelung fluid model with dissipation which is linearazible in the form of Schrödinger equation with time variable coefficients. The corresponding complex Burgers equation is solved ...

Exact quantization of CauchyEuler type forced parametric oscillator
(IOP Publishing, 201610)Driven and damped parametric quantum oscillator is solved by WeiNorman Lie algebraic approach, which gives the exact form of the evolution operator. This allows us to obtain explicitly the probability densities, timeevolution ... 
Exact solutions of a fractionaltype differentialdifference equation related to discrete MKdV equation
(IOP Publishing, 201405)The extended simplest equation method is used to solve exactly a new differentialdifference equation of fractionaltype, proposed by Narita [J. Math. Anal. Appl. 381 (2011) 963] quite recently, related to the discrete ... 
Filamentary structures of the cosmic web and the nonlinear Schrödinger type equation
(IOP Publishing, 2011)We show that the filamentary type structures of the cosmic web can be modeled as solitonic waves by solving the reaction diffusion system which is the hydrodynamical analogous of the nonlinear Schrödinger type equation. ... 
From qanalytic functions to double qanalytic Hermite binomials and qtraveling waves
(IOP Publishing, 201610)We extend the concept of qanalytic function in two different directions. First we find expansion of qbinomial in terms of qHermite polynomials, analytic in two complex arguments. Based on this representation, we introduce ... 
Golden quantum oscillator and BinetFibonacci calculus
(IOP Publishing, 201201)The Binet formula for Fibonacci numbers is treated as a qnumber and a qoperator with Golden ratio bases q = and Q = 1/, and the corresponding Fibonacci or Golden calculus is developed. A quantum harmonic oscillator for ... 
Hamiltonian dynamics of N vortices in concentric annular region
(IOP Publishing, 201105)The problem of N vortex dynamics in annular domain is considered. The region is canonical one and allows by conformal mapping apply results to an arbitrary position of two cylinders in the plane. Using previous solution, ... 
Identification of bquark jets with the CMS experiment
(IOP Publishing, 201304)At the Large Hadron Collider, the identification of jets originating from b quarks is important for searches for new physics and for measurements of standard model processes. A variety of algorithms has been developed by ...
