Direct Similarity Reduction of Variable Coefficient KdV Equation
Yang Zengqiang · Journal of Shihezi University · 2010
The manipulation of the direct similarity reduction method(presented by Clarkson and Kruskal(CK method)) is improved,and then applied to a variable coefficients KdV equation.More similarity reductions were obtained.Simultaneity the restriction,which is against the coefficients of the vcKdV that obtained from consistent condition,is more general.
