Erratum to: ‘‘Multiple-soliton solutions for the ninth-order KdV equation and sixth-order Boussinesq equation” [Appl. Math. Comput. 203 (2008) 277–283] Abdul-Majid Wazwaz Department of Mathematics, Saint Xavier University, Chicago, IL 60655, United States

1. In page 282, there is a misprint in Eq. (47) which should be changed to

b123 –a12 a13 a23 :

ð47Þ

The next paragraph to Eq. (47) should be changed to: The three-soliton solutions do not exist for the ninth-order equation. Based on this, we conclude that the ninth-order KdV equation is not completely integrable. 2. In page 282, there is a misprint in Eq. (60) which should be changed to

b123 –a12 a13 a23 :

ð60Þ

The next paragraph to Eq. (60) should be changed to: The three-soliton solutions do not exist for the sixth-order equation. Based on this, we conclude that the sixth-order Boussinesq equation is not completely integrable.
