梯度系统的共形不变性与Mei守恒量
Conformal Invariance and Mei Conserved Quantity of Gradient System
摘要
Abstract
The conformal invariance and Mei symmetry of the gradient system under infinitesimal transformations were considered.The author gave the definition and determining equations of Mei symmetry and Mei conserved quantity of the gradient system.The necessary and sufficient condition that conformal invariance of the gradient system would be Mei symmetry was given.Mei conserved quantity deduced from conformal invariance was obtained by making use of Mei symmetry.关键词
