Approximate solution of stochastic Volterra integro-differential equations by using moving least squares scheme and spectral collocation method

作者:

Highlights:

• Our method is an attractive and easy idea using moving least squares (MLS) and the spectral collocation method to estimate the solution of nonlinear stochastic Volterra integro-differential equations.

• An essential advantage of the proposed technique is that it does not require any preprocessing, such as mesh refinement. Therefore, this method is independent of the geometry of the domains.

• A significant advantage of our approach is that it provided acceptable results with a small number of points and basis functions.

• This method can be used to solve problems with smooth and nonsmoth solution.
