This research aims to solve Differential Algebraic Equation (DAE) problems in their original form, wherein both the differential and algebraic equations remain. The Newton or Newton-Broyden technique along with some integrators such as the Runge-Kutta method is coupled together to solve the problems. Experiments show that the method developed in this paper is efficient, as it demonstrates that
2013-11-01 · In this paper, we consider fractional differential equations with delay. We focus on linear equations. We summarise existence and uniqueness theory based on the method of steps and we give a theorem on the propagation of derivative discontinuities.
The basis of their method is the numerical determination of the coefficients of the Fourier cosine or sine 2018-01-15 The first approach is based on a direct discretisation of the fractional differential operator: we obtain a numerical method for solving a linear fractional differential equation with order 0<α<1. In this paper, we propose a new kind of numerical simulation method for backward stochastic differential equations (BSDEs). We discretize the continuous BSDEs on time‐space discrete grids, use the Monte Carlo method to approximate mathematical expectations, and use space interpolations to compute values at non‐grid points. 2012-03-20 Numerical Methods for Partial Differential Equations. 1,811 likes · 161 talking about this.

2018-01-15 · In this paper we are concerned with numerical methods to solve stochastic differential equations (SDEs), namely the Euler-Maruyama (EM) and Milstein methods. These methods are based on the truncated Ito-Taylor expansion. In our study we deal with a nonlinear SDE. We approximate to numerical solution using Monte Carlo simulation for each method. Also exact solution is obtained from Ito’s
