LIE SYMMETRY ANALYSIS AND EXACT SOLUTION OF (2+1)-DIMENSIONAL KADOMTSOV-PETVIASHVILI-JOSEPH-EGRI EQUATION
摘要
Abstract
Based on the classical Lie group method, we obtain the classical Lie point symmetry of the (2+1)-dimensional Kadomtsov-Petviashvili-Joseph-Egri (KP-JE for short) equation. Using the symmetries, we find some classical similarity reductions of KP-JE equation. Many kinds of exact solutions of the KP-JE equation are derived by solving the reduced equations, including the elliptic functions , the rational functions,the hyperbolic functions, the trigonometric functions, the power series solution.关键词
