| Abstract: | The degree theory was applied to deal with a discrete nonlinear reaction diffusion equation. The existence condition of travelling wavefront whutions were obtained. In me hypothetic conditions, it was showed that the solutions of modified discrete equation converged to travelling wavefront soutions of the continous equation. |
