摘要

Applying the consistent Riccati expansion method,the extended (2+-1)-dimensional shallow water wave equation is proved consistent Riccati solvable and the exact interaction solutions including soliton-cnoidal wave solutions,solitoff-typed solutions are obtained.With the help of the truncated Painlevé expansion,the corresponding nonlocal symmetry is also given,and furthermore,the nonlocal symmetry is localized by prolonging the related enlarged system.
