摘要
There is the widespread existence of wave phenomena in physics, chemistry and biology. This clearly necessitates a study of traveling waves in depth and of the modeling and analysis involved. In the present paper, we study the Fisher equation by means of the first integral method, which is based on the ring theory of commutative algebra. A traveling wave solution is obtained, which indicates that the analytical solutions in the literature are particular cases of our result. (c) 2005 Elsevier B.V. All rights reserved.
