Interaction solutions for mKP equation with nonlocal symmetry reductions   and CTE method
  The nonlocal symmetries for the modified Kadomtsev-Petviashvili (mKP) equation are obtained with the truncated Painleve method. The nonlocal symmetries can be localized to the Lie point symmetries by introducing auxiliary dependent variables. The finite symmetry transformations and similarity reductions related with the nonlocal symmetries are computed. The multi-solitary wave solution and interaction solutions among a soliton and the cnoidal waves of the mKP equation are presented. In the meanwhile, the consistent tanh expansion (CTE) method is applied to the mKP equation. The explicit interaction solutions among a soliton and other types of nonlinear waves such as the cnoidal periodic waves and multiple resonant soliton solutions are given.
