Chapter 5 considers two mechanization algorithm of jacobian function solutions based on sine - gordon and sinh - gordou equations 在解決問題的過程中吳代數(shù)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 稱之為雅可比橢圓函數(shù)擴(kuò)展法,它是一種比sine - cosine方法和sn - cn函數(shù)法,雙曲函數(shù)法更有效和簡(jiǎn)單的方法。
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 我們分別把它應(yīng)用于一類非線性演化方程, rlw和組合kdv方程上去,獲得了許多雅可比橢圓函數(shù)解和其它精確解。
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 第二部分以構(gòu)造性的變換及符號(hào)計(jì)算特別是(吳代數(shù)消元法)為工具,來(lái)研究非線性演化方程中的一些問題:精確解(如孤子解、周期解、有理解和雅可比橢圓函數(shù)解(雙周期解)等) 、 backlund變換、 hopf變換, dromion解及衰變結(jié)構(gòu)等第二章介紹了求解pdes的ac = bd模式及其在偏微分方程中的作用。
