Vertical stability of circular orbits in relativistic razor-thin disks [PDF]
, 2016 During the last few decades, there has been a growing interest in exact solutions of Einstein equations describing razor-thin disks. Despite the progress in the area, the analytical study of geodesic motion crossing the disk plane in these systems is not

Extended modified cubic B-spline algorithm for nonlinear Burgers' equation
Beni-Suef University Journal of Basic and Applied Sciences, 2016 In this paper, an extended modified cubic B-Spline differential quadrature method is proposed to approximate the solution of the nonlinear Burgers' equation. The proposed method is used in space and a five-stage and four order strong stability-preserving

Strong Stability Preserving Runge–Kutta and Linear Multistep Methods
Bulletin of the Iranian Mathematical Society, 2022 AbstractThis paper reviews strong stability preserving discrete variable methods for differential systems. The strong stability preserving Runge–Kutta methods have been usually investigated in the literature on the subject, using the so-called Shu–Osher representation of these methods, as a convex combination of first-order steps by forward Euler ...

Numerical Simulation of a Space-Fractional Molecular Beam Epitaxy Model without Slope Selection
Fractal and Fractional, 2023 In this paper, we introduce a space-fractional version of the molecular beam epitaxy (MBE) model without slope selection to describe super-diffusion in the model. Compared to the classical MBE equation, the spatial discretization is an important issue in

Strong Stability Preserving Properties of Composition Runge–Kutta Schemes [PDF]
Journal of Scientific Computing, 2019 In this paper Strong Stability Preserving (SSP) properties of Runge Kutta methods obtained by com- posing k different schemes with different step sizes are studied. The SSP coefficient of the composition method is obtained and an upper bound on this coefficient is given. Some examples are shown.
