Travelling wave solutions for time-delayed nonlinear evolution equations. (English) Zbl 1189.35281
Summary: Time-delayed nonlinear evolution equations have a wide range of applications in science and engineering. In this paper, the (G ' G)-expansion method is implemented to establish travelling wave solutions for time-delayed Burgers and time-delayed Burgers-Fisher equations. The travelling wave solutions are expressed by hyperbolic functions and trigonometric functions. The results reveal that (G ' G)-expansion method is very effective and a powerful tool for solving nonlinear time-delayed evolution equations arising in mathematical physics.
