【 摘 要 】

The method of obtaining inverse integrating factors of n-th order autonomous systems using one-parameter Lie groups admitted by the systems is given. By describing n-th order autonomous systems with differential form systems, the properties of inverse integrating factors of the n-th order autonomous systems are presented. (C) 2011 Elsevier Inc.
