关于发展方程的接触对称性

On contact symmetries of evolution equations

Qing Huang, Renat Zhdanov, Changzheng Qu

摘要:

在本文中,我们发展了一种代数方法来分类二阶非线性发展方程的接触对称性。直到接触同构,所有不等价的偏微分方程承认半单代数,可解代数的尺寸$n\leq4$,代数有非平凡的Levi因子,属于所考虑的类,和相应的接触对称,他们承认列出。

英文摘要:

In this paper, we develop an algebraic approach to classifying contact symmetries of the second-order nonlinear evolution equations. Up to contact isomorphisms, all inequivalent PDEs admitting semi-simple algebras, solvable algebras of dimension $n\leq4$, and algebras having nontrivial Levi factors, belonging to the class under consideration, and corresponding contact symmetries they admitted are listed.
