Z. Naturforsch.65a,197 – 202 (2010); received November 12, 2008 / revised July 28, 2009 In this paper, the exp-function method is applied by using symbolic computation to construct a variety of new generalized solitonary solutions for the Chaffee-Infante equation with distinct phys- ical structures. The results reveal that the exp-function method is suited for finding travelling wave solutions of nonlinear partial differential equations arising in mathematical physics.

Key words:Chaffee-Infante Equations; Solitonary Solutions; Travelling Wave Solutions;
