A Study On Stability Of Conditional Variances For GARCH Models With Application
Tikrit Journal of Pure Science, 2023 In this paper we study the stability conditions of GARCH models and we find these conditions by using a local linearization technique. In addition we study the stability of conditional variances predictions where these predictions converge to an ...

Characterizing the stabilization size for semi-implicit Fourier-spectral method to phase field equations [PDF]
, 2016 Recent results in the literature provide computational evidence that stabilized semi-implicit time-stepping method can efficiently simulate phase field problems involving fourth-order nonlinear dif- fusion, with typical examples like the Cahn-Hilliard ...

Mathematics, 2022 In this paper, we consider numerical approximations of the Cahn–Hilliard type phase-field crystal model and construct a fully discrete finite element scheme for it. The scheme is the combination of the finite element method for spatial discretization and

Entropy, 2022 In this paper, a new decoupling method is proposed to solve a nematic liquid crystal flow with stretching effect. In the finite element discrete framework, the director vector is calculated by introducing a new auxiliary variable w, and the velocity ...

An iterative decoupled algorithm with unconditional stability for Biot model
Mathematics of Computation, 2023 This paper is concerned with numerical algorithms for Biot model. By introducing an intermediate variable, the classical 2-field Biot model is written into a 3-field formulation. Based on such a 3-field formulation, we propose a coupled algorithm, some time-extrapolation based decoupled algorithms, and an iterative decoupled algorithm. Our focus is the

Higher-order approximations for space-fractional diffusion equation
Journal of Numerical Analysis and Approximation TheorySecond-order and third-order finite difference approximations for fractional derivatives are derived from a recently proposed unified explicit form. The Crank-Nicholson schemes based on these approximations are applied to discretize the space-fractional

Vector Additive Decomposition for 2D Fractional Diffusion Equation
Nonlinear Analysis, 2008 Such physical processes as the diffusion in the environments with fractal geometry and the particles’ subdiffusion lead to the initial value problems for the nonlocal fractional order partial differential equations. These equations are the generalization
