In this paper , we convert the complex third order eigenvalue problems into the real third order eigenvalue problems . then , based on the euler - lagrange equation and legendre transformation , a reasonable jacobi - ostrogredsky coordinate system have been found , then using nonlinear method , the lax pairs of the real bargrnann and neumann system are nonlinearized , so as to be a new finite - dimensional integrable hamilton system in the liouville sense is generated . moreover , the involutive representations of the solution for the evolution equations are obtained 本文將復(fù)的三階特征值問題轉(zhuǎn)化為實的三階特征值問題,利用euler - lagrange方程和legendre變換,找到一組合理的實的jacobi - ostrogredsky坐標系,從而找到與之相關(guān)的實化系統(tǒng),再利用曹策問教授的非線性化方法,分別將三階特征值問題及相應(yīng)的lax對進行非線性化,從而得到bargmann勢和neumann勢約束系統(tǒng),并證明它們是liouville意義下的完全可積系統(tǒng),進而給出了bargmann系統(tǒng)和neumann系統(tǒng)的對合解。
