چکیده
We propose a new symmetry reduction method for (1+1)-dimensional differential-difference equations (DDEs), namely, the λ -symmetry of solving ordinary differential is generalized to DDEs. Order-reduction processes are consequence invariance given DDE under vector fields class. These satisfy prolongation formula. A simple example order-reduction provided illustrate application.

Finite difference method for solving partial integro-differential equations
In this paper, we have introduced a new method for solving a class of the partial integro-differential equation with the singular kernel by using the finite difference method. First, we employing an algorithm for solving the problem based on the Crank-Nicholson scheme with given conditions. Furthermore, we discrete the singular integral for solving of the problem. Also, the numerical results ob...
متن کاملNonstandard finite difference schemes for differential equations
In this paper, the reorganization of the denominator of the discrete derivative and nonlocal approximation of nonlinear terms are used in the design of nonstandard finite difference schemes (NSFDs). Numerical examples confirming then efficiency of schemes, for some differential equations are provided. In order to illustrate the accuracy of the new NSFDs, the numerical results are compared with ...
