Squeezing and resonance in a generalized Caldirola-Kanai type quantum parametric oscillator
(American Institute of Physics, 2018-08)The evolution operator of a Caldirola-Kanai type quantum parametric oscillator with a generalized quadratic Hamiltonian is obtained using the Wei-Norman Lie algebraic approach, and time evolution of the eigenstates of a ... -
Complex Ginzburg–Landau equations with dynamic boundary conditions
(Elsevier, 2018-06)The initial-dynamic boundary value problem (idbvp) for the complex Ginzburg–Landau equation (CGLE) on bounded domains of RN is studied by converting the given mathematical model into a Wentzell initial–boundary value problem ... -
Conditioning and error analysis of nonlocal operators with local boundary conditions
(Elsevier, 2018-06)We study the conditioning and error analysis of novel nonlocal operators in 1D with local boundary conditions. These operators are used, for instance, in peridynamics (PD) and nonlocal diffusion. The original PD operator ... -
Poor modules with no proper poor direct summands
(Elsevier, 2018-05)As a mean to provide intrinsic characterizations of poor modules, the notion of a pauper module is introduced. A module is a pauper if it is poor and has no proper poor direct summand. We show that not all rings have pauper ... -
A boundary integral equation for the transmission eigenvalue problem for Maxwell equation
(Wiley, 2018-03)We propose a new integral equation formulation to characterize and compute transmission eigenvalues in electromagnetic scattering. As opposed to the approach that was recently developed by Cakoni, Haddar and Meng (2015) ... -
Rugged modules: The opposite of flatness
(Taylor & Francis Group, 2018-02)Relative notions of flatness are introduced as a mean to gauge the extent of the flatness of any given module. Every module is thus endowed with a flatness domain and, for every ring, the collection of flatness domains of ... -
Reidemeister torsion and orientable punctured surfaces
(Korean Mathematical Society, 2018)Let Σg,n,b denote the orientable surface obtained from the closed orientable surface Σg of genus g ≥ 2 by deleting the interior of n ≥ 1 distinct topological disks and b ≥ 1 points. Using the notion of symplectic chain ... -
Boosting the decay of solutions of the linearised Korteweg-de Vries–Burgers equation to a predetermined rate from the boundary
(Taylor & Francis, 2019)The aim of this article is to extend recent results on the boundary feedback controllability of the Korteweg-de Vries equation to the Korteweg-de Vries–Burgers equation which is posed on a bounded domain. In the first part ... -
Injective modules over down-up algebras
(Cambridge University Press, 2010)The purpose of this paper is to study finiteness conditions on injective hulls of simple modules over Noetherian down-up algebras. We will show that the Noetherian down-up algebras A(α, β, γ) which are fully bounded are ... -
Measurement of the W-boson helicity in top-quark decays from tt̄ production in lepton+jets events in pp collisions at√s = 7 TeV Th
(Springer, 2013-10)The W-boson helicity fractions in top-quark decays are measured with tt̄ events in the lepton+jets final state, using proton-proton collisions at a centre-of-mass energy of 7TeV, collected in 2011 with the CMS detector at ... -
The Hirota Method for reaction-diffusion equations with three distinct roots
(AIP Publishing, 2004)The Hirota Method, with modified background is applied to construct exact analytical solutions of nonlinear reaction-diffusion equations of two types. The first equation has only nonlinear reaction part, while the second ... -
Hirota method for solving reaction-diffusion equations with generalized nonlinearity
(World Academic Press, 2006)The Hirota Method is applied to find an exact solitary wave solution to evolution equation with generalized nonlinearity. By introducing the power form of Hirota ansatz the bilinear representation for this equation is ... -
An operator splitting approximation combined with the supg method for transport equations with nonlinear reaction term
(Tech Science Press, 2012)In this work, an operator splitting method is proposed in order to obtain a stable numerical solution for transport equation with non-linear reaction term. We split the transport equation into a reaction part and an ... -
A conserved linearization approach for solving nonlinear oscillation problems
(Natural Sciences Publishing, 2018-05)Nonlinear oscillation problems are extensively used in engineering and applied sciences. Due to non-availability of the analytic solutions, numerical approaches have been used for these equations. In this study, a numerical ... -
