二维广义Burgers方程的无穷维对称性

Infinite-dimensional symmetries of a two-dimensional generalized Burgers equation

F. Gungor

摘要:

本文给出了一个广义Burgers方程的条件,该方程先验地包含九个一元或二元的任意函数,并给出了该方程的无穷维对称代数的存在条件。虽然这个代数可以包含两个任意的时间函数,但它不允许有一个维拉索罗代数。这一结果证实了不可积方程的变系数推广应该保持不变。

英文摘要:

The conditions for a generalized Burgers equation which a priori involves nine arbitrary functions of one, or two variables to allow an infinite dimensional symmetry algebra are determined. Though this algebra can involve up to two arbitrary functions of time, it does not allow a Virasoro algebra. This result confirms that variable coefficient generalizations of a non-integrable equation should be expected to remain as such.
