Firstly, a direct algebraic method and a routine way in finding traveling wave solutions to nonlinear evolution equations are explained. And then some new exact solutions for some evolution equations are obtained by u...
In this paper, a restraint operator is used to improve the stability of the Chebyshev spectral method. The generalized stability of this new method is proved and the rate of convergence is analyzed. The numerical resu...
