Chapter 5 considers two mechanization algorithm of jacobian function solutions based on sine - gordon and sinh - gordou equations 在解决问题的过程中吴代数消元法是最重要的基本工具。
We call above two mechanization algorithm as jacobian function expension method . the jacobian function expension method is an effective method than the sine - consine method and the sn - cn method 称之为雅可比椭圆函数扩展法,它是一种比sine - cosine方法和sn - cn函数法,双曲函数法更有效和简单的方法。
Finally we apply jacobian function expension method to a class of nonlinear evolution equations , rlw and a compound kdv equations and get many new jacobian function solutions and solitary wave solutions 我们分别把它应用于一类非线性演化方程, rlw和组合kdv方程上去,获得了许多雅可比椭圆函数解和其它精确解。
The second part , with the aid of many types constructive transformation and symbolic computation ( especially wu algebraic elemination method ) , some topics in nonlinear evolution equation are studied , including exact solution ( solitary solution , periodic solution , rational function solutions and jacobian function solution ) , backlund transformation , cole - hopf transformation , dromion solution and its construction etc . charter 2 introduces ac = bd model and its application about partial differential equations 第二部分以构造性的变换及符号计算特别是(吴代数消元法)为工具,来研究非线性演化方程中的一些问题:精确解(如孤子解、周期解、有理解和雅可比椭圆函数解(双周期解)等) 、 backlund变换、 hopf变换, dromion解及衰变结构等第二章介绍了求解pdes的ac = bd模式及其在偏微分方程中的作用。
