Q-条件对称在局部变换群下的等价性

Equivalence of Q-Conditional Symmetries under Group of Local Transformation

Roman O. Popovych

摘要:

将偏微分方程的Q-条件对称性的定义正确地推广到偏微分方程系统和对合算子族的特殊情况。引入了Q-条件对称在一组局部变换下等价的概念。利用这个概念,所有可能的单Q-条件对称算子被分类为n维(n >= 2)线性热方程和描述不可压缩理想流体运动的欧拉方程。

英文摘要:

The definition of Q-conditional symmetry for one PDE is correctly generalized to a special case of systems of PDEs and involutive families of operators. The notion of equivalence of Q-conditional symmetries under a group of local transformation is introduced. Using this notion, all possible single Q-conditional symmetry operators are classified for the n-dimensional (n >= 2) linear heat equation and for the Euler equations describing the motion of an incompressible ideal fluid.
