چکیده

We consider a complex autonomously driven single limit cycle oscillator with delayed feedback.The original model is translated to a two-dimensional system.Through a nonstandard finite-difference (NSFD) schemewe study the dynamics of this resulting system. The stability of the equilibriumof themodel is investigated by analyzing the characteristic equation. In the two-dimensional discrete model, we find that there are stability switches on the time delay and Hopf bifurcation when the delay passes a sequence of critical values. Finally, computer simulations are performed to illustrate the theoretical results. And the results show that NSFD scheme is better than the Euler method.

A new total variation diminishing implicit nonstandard finite difference scheme for conservation laws

In this paper, a new implicit nonstandard finite difference scheme for conservation laws, which preserving the property of TVD (total variation diminishing) of the solution, is proposed. This scheme is derived by using nonlocal approximation for nonlinear terms of partial differential equation. Schemes preserving the essential physical property of TVD are of great importance in practice. Such s...
