【Abstract】 In this paper, we discuss the strong symmetries and symmetries for the generalized Burger equation uI = F2u + Fu2 (F is a first order linear partial differential operator independent of t) . We present two strong symmetries, three groups of symmet-ries σm,n,∑m ,n and tm,n and Lie algebra that the symmetries satisfy.更多还原
