Abstract
Based on the closed connections among the homogeneous balance (HB) method, Weiss-Tabor-Cameval (WTC) method and Clarkson-Kruskal (CK) method, we study Backlund transformation and similarity reductions of the variable coefficients variant Boussinesq system. In the meantime, new exact solutions also are found. (c) 2007 Elsevier B.V. All rights reserved.
