Non-Standard Finite Difference Schemes for Solving Singular Lane-Emden Equation [PDF]
International Journal of Research in Industrial Engineering, 2017 In this paper we construct Non-Standard finite difference schemes (NSFD) for numerical solution of nonlinear Lane-Emden type equations which are nonlinear ordinary dierential equations on semi-infinite domain.

A fully implicit non-standard finite difference scheme for one dimensional Burgers' equation
Journal of Applied Research on Industrial Engineering, 2020 In this paper we have studied a numerical approximation to the solution of the nonlinear Burgers' equation. The presented scheme is obtained by using the Non-Standard Finite Difference Method (NSFD).

High-order Compact Difference Schemes for the Modified Anomalous Subdiffusion Equation [PDF]
, 2015 In this paper, two kinds of high-order compact finite difference schemes for second-order derivative are developed. Then a second-order numerical scheme for Riemann-Liouvile derivative is established based on fractional center difference operator.

Error bounds for monotone approximation schemes for parabolic Hamilton-Jacobi-Bellman equations [PDF]
, 2006 We obtain non-symmetric upper and lower bounds on the rate of convergence of general monotone approximation/numerical schemes for parabolic Hamilton Jacobi Bellman Equations by introducing a new notion of consistency.

A monotone predictor-corrector scheme for advection
Computer Assisted Methods in Engineering and Science, 2023 A monotone predictor- corrector finite difference scheme solving the advection equation has been proposed. A geometrical interpretation of the Burstein scheme forms a basis for construction of the new scheme.
