| Abstract: | Based on computer symbolic system,a modified hyperbolic function method is presented to search for exact solutions of differential-difference equations.The(2+1)-dimensional Toda lattice is chosen to illustrate the method.As a result,abundant new solitary solutions are obtained.The method can be applied to many other nonlinear differential-different equations(DDEs). |
