广义Boussinesq方程的经典对称性与非经典对称性

Classical and nonclassical symmetries of a generalized Boussinesq equation

Maria Luz Gandarias, M. S. Bruzón

摘要:

本文利用李群方法和Bluman和Cole的非经典方法推导了广义Boussinesq方程的对称性,其中经典Boussinesq方程是其特例.我们研究了函数类$f(u)$,该方程允许经典或非经典的方法。得到的减少是派生的。可以导出一些新的精确解。

英文摘要:

We apply the Lie-group formalism and the nonclassical method due to Bluman and Cole to deduce symmetries of the generalized Boussinesq equation, which has the classical Boussinesq equation as an special case. We study the class of functions $f(u)$ for which this equation admit either the classical or the nonclassical method. The reductions obtained are derived. Some new exact solutions can be derived.
