摘要
In this paper, we consider a new class of nonlinear partial differential equations with nonlinear term of any order, u(tt) + a(1)u(xx) + a(2)u + a(3)u(P) + a(4)u(2P-1) = 0, which contains some particular important equations. We give a new kind of transformation and a new generalized ansatze to treat this class of equations. As a result, many explicit exact solutions, which contain new kink-profile solitary-wave solutions, bell-profile solitary-wave solutions, periodic wave solutions and combined formal solitary-wave solutions, are obtained by the extended method. In addition, we also can derive rational solutions for this class of equations. (C) 2003 Elsevier Science Ltd. All rights reserved.
