New Exact Solutions to the Nonlinear Spatiotemporal Fractional-order Telegraphic Equation Based on the G′/G^2 Expansion Method with Negative or Non-negative Power Terms

本文使用含负幂项与非负幂项的G′/G^2展开法,借助Maple软件构建非线性时空分数阶电报方程的新精确解.这些新精确解包括三角函数精确解、双曲函数精确解和有理函数精确解,与文献[11]中得到的精确解不同.

In this paper some new exact solutions to the nonlinear spatiotemporal fractional telegraph equation are constructed by using the G′/G2 expansion method with negative power terms or with non-negative power terms and applying the software Maple.The new exact solutions include solutions of trigonometric functions,hyperbolic functions and rational functions,which are new to the solutions in[11].
