Some finite difference methods for solving linear fractional KdV equation

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
The time-fractional Korteweg de Vries equation can be viewed as a generalization of the classical KdV equation. The KdV equations can be applied in modeling tsunami propagation, coastal wave dynamics, and oceanic wave interactions.

Finite Difference Methods for the BSDEs in Finance

open access: yesInternational Journal of Financial Studies, 2018
This paper gives a review of numerical methods for solving the BSDEs, especially, finite difference methods. For numerical methods of finite difference, we should divide them into three branches.

A Comparison of Finite Difference and Finite Volume Methods with Numerical Simulations: Burgers Equation Model

open access: yesComplexity, 2022
In this paper, we present an intensive investigation of the finite volume method (FVM) compared to the finite difference methods (FDMs). In order to show the main difference in the way of approaching the solution, we take the Burgers equation and the ...

Stabilized finite difference methods for the fully dynamic biot's problem

open access: yesMathematical Modelling and Analysis, 2013
This paper deals with the stabilization of the poroelasticity system, in the incompressible fully dynamic case. The stabilization term is a perturbation of the equilibrium equation that allows us to use central difference schemes to approximate the first
