一维Hamilton-Jacobi方程的通解

General Solution to Unidimensional Hamilton-Jacobi Equation

Maria Lewtchuk Espindola

摘要:

基于类Legendre变换和一个Pfronan微分形式定理,给出了求解偏微分方程\ $F(u_x,u_y)=0$ ; \ $F(f(x)\:u_x,u_y)=0$ \(或\ $F(u_x,h(y)\:u_y)=0$)\通解的一种方法.由于所得到的解依赖于任意函数,因此它是通解。作为方法的推广,得到了偏微分方程的通解:\ $F(f(x)\:u_x,u_y)=G(x)$,并将其应用于一维Hamilton-Jacobi方程.

英文摘要:

A method for finding the general solution to the partial differential equations: \ $F(u_x,u_y)=0$; \ $F(f(x)\:u_x,u_y)=0$ \ (or \ $F(u_x,h(y)\:u_y)=0$) \ is presented, founded on a Legendre like transformation and a theorem for Pfaffian differential forms. As the solution obtained depends on an arbitrary function, then it is a general solution. As an extension of the method it is obtained a general solution to PDE: \ $F(f(x)\:u_x,u_y)=G(x)$, and then applied to unidimensional Hamilton-Jacobi equation.
