Symmetry group theorem to the Lin-Tsien equation and conservation laws
relating to the symmetry of the equation? [PDF]
Liu Xi-ZhongIn this paper, We derive the symmetry group theorem to the Lin-Tsien equation by using the modified CK's direct method, from which we obtain the corresponding symmetry group. More importantly, conservation laws corresponding to the Kac-Moody-Virasoro symmetry algebra of Lin-Tsien equation is obtained up to second order group invariants.View original: http://arxiv.org/abs/1211.1786
