Lie group analysis for short pulse equation (1201.3431v1)
Published 17 Jan 2012 in math.AP
Abstract: In this paper, the classical Lie symmetry analysis and the generalized form of Lie symmetry method are performed for a general short pulse equation. The point, contact and local symmetries for this equation are given. In this paper, we generalize the results of H. Liu and J. Li [1], and add some further facts, such as optimal system of Lie symmetry subalgebras and two local symmetries.
