Jacobi椭圆函数新的展开法对非线性耦合标量场方程双周期解的求解

The New Jacobi Elliptic Function Expansion Method Applied to Nonlinear Coupled Scalar Field Equation

推广了Jacobi椭圆函数展开方法,引入Jacobi椭圆函数的负幂次展开,研究了非线性耦合标量场方程组的求解问题,得到了新的非线性耦合标量场方程组的双周期解.

In this paper, the Jacobi elliptic function method is generalized to study nonlinear coupled scalar field equation. The doubly-periodic solutions of nonlinear coupled scalar field equation are obtained, and some new solutions are obtained.
