摘要🙇🏿♂️:The study of Lie point symmetry is considered to be one of most effective methods for finding invariant solutions. Exact solutions of partial differential equations can be given by the Lie point method. Besides Lie point symmetry, the nonlocal symmetries which can be obtained by the algorithmic approach, inverse recursion operators, Mobious (conformal) invariant form, Darboux transformation, and Backlund transformation, are proposed. In this talk, the Lie point and nonlocal symmetry in partial differential equations will be briefly introduced. The interaction solutions among different nonlinear excitations are obtained by the localization of the nonlocal symmetry to the Lie point symmetry. Finally, some of their applications are given.
