“…The classic nonlinear dispersive Kðm; nÞ equation first introduced by Rosenau and Hymann (1993) and for certain values of m and n, Kðm; nÞ equation has solitary waves which are compactly supported. Recently, large number of methods were suggested to study the nonlinear dispersive Kðm; nÞ equations, such as Adomian method (Wazwaz, 2002(Wazwaz, , 2003(Wazwaz, , 2004Zhu et al, 2007), Exp-function method (He and Wu, 2006a), variational iteration method (He and Wu, 2006b;Wazwaz, 2007;Tian and Yin, 2007), variational method (He, 2006a, b) and HPM (He, 2005a, b;Odibat, 2007). There are also many effective and convenient methods for solving these type equations (Inç, 2006;Zhu and Lu, 2006;Zhu and Gao, 2006;Tian and Yin, 2005).…”
