An Explicit–Implicit Spectral Element Scheme for the Nonlinear Space Fractional Schrödinger Equation
Fractal and Fractional, 2023 In this paper, we solve the space fractional nonlinear Schrödinger equation (SFNSE) by developing an explicit–implicit spectral element scheme, which is formulated based on the Legendre spectral element approximation in space and the Crank–Nicolson leap ...

An optimized finite difference Crank-Nicolson iterative scheme for the 2D Sobolev equation
Advances in Difference Equations, 2017 In this paper, we devote ourselves to establishing the unconditionally stable and absolutely convergent optimized finite difference Crank-Nicolson iterative (OFDCNI) scheme containing very few degrees of freedom but holding sufficiently high accuracy for

Fractal and Fractional, 2022 This paper aims to numerically study the time-fractional Allen-Cahn equation, where the time-fractional derivative is in the sense of Caputo with order α∈(0,1). Considering the weak singularity of the solution u(x,t) at the starting time, i.e., its first

Spectral stability for a class of fourth order Steklov problems under domain perturbations [PDF]
, 2019 We study the spectral stability of two fourth order Steklov problems upon domain perturba- tion. One of the two problems is the classical DBS\u2014Dirichlet Biharmonic Steklov\u2014problem, the other one is a variant. Under a comparatively weak condition

Difference functional inequalities and applications [PDF]
Opuscula Mathematica, 2014 The paper deals with the difference inequalities generated by initial boundary value problems for hyperbolic nonlinear differential functional systems. We apply this result to investigate the stability of constructed difference schemes.

Stability for a GNS inequality and the Log-HLS inequality, with application to the critical mass Keller-Segel equation [PDF]
, 2011 Starting from the quantitative stability result of Bianchi and Egnell for the 2-Sobolev inequality, we deduce several different stability results for a Gagliardo-Nirenberg-Sobolev inequality in the plane.

Entropy, 2023 The stability and convergence analysis of a multivariable stochastic self-tuning system (STC) is very difficult because of its highly nonlinear structure. In this paper, based on the virtual equivalent system method, the structural nonlinear or nonlinear

Family Stability and Labor Market Gender Convergence [PDF]
SSRN Electronic Journal, 2009 The present paper examines the historical development in the structure of the family in terms of marriage, divorce, fertility and labor 1886-2007 in order to map quantitative changes. The paper draws new information from novel Norwegian data. Along with the changing family relations we also quantify the closing of the gender gap by converging trends ...
