The paper presents a number of new exact solutions to nonlinear reaction–diffusion equations with delay of the form where is the delay time, and is an arbitrary function of two arguments. Solutions are sought in the form of a generalized traveling-wave, with . It is shown that one of the two functional coefficients and of the equation considered can be specified arbitrarily. Examples of delay reaction–diffusion equations and their solutions are given. New exact solutions of few other nonlinear delay PDEs are also obtained. 相似文献
