Lie Symmetry and Conserved Quantity of three-order lagrangian equations for Non-conserved Mechanical System
收藏 引用
Communications in Theoretical Physics 2006年 第2期45卷 350-352页
作者: MA Shan-Jun YANG Xue-Hui YAN Rong HUANG Pei-Tian College of Physics and Communication Electronics Jiangxi Normal University Nanchang 330027 China
Based on the infinitesimal and one parameter transformation, the problem of Lie symmetry of three-order lagrangian equations has been studied. Under Lie transformation, the sufficient and necessary condition which kee... 详细信息
