【摘要】：利用預(yù)李群分類法給出方程u_t-u_(xx)=f(t,x,u)的群不變解和f的解析表達(dá)式;應(yīng)用Tanh函數(shù)法和試探-函數(shù)法找到Fitzhugh-Nagumo方程u_t-u_(xx)=u(1-u)(u-a),-1≤a≤1的許多新的顯示解析行波解.
[Abstract]:The group invariant solution and the analytic expression of f of the equation u _ (xx) f (TX) are given by using the pre-Li Qun classification method, and many new solutions of the Fitzhugh-Nagumo equation ut-u _ (xx) u (1-u) (u-a) -1 鈮，
