给出一类特定多项式型的九阶偏微分方程的Frobenius可积分解。具有Frobenius可积分解的两类偏微分方程与因变量的两个有理Bäcklund变换相联系。给出的偏微分方程是常系数方程,相应的可积常微分方程具有高阶非线性。该方法也可以很容易地推广到变系数偏微分方程的研究中。
Frobenius integrable decompositions are presented for a kind of ninth-order partial differential equations of specific polynomial type. Two classes of such partial differential equations possessing Frobenius integrable decompositions are connected with two rational Bäcklund transformations of dependent variables. The presented partial differential equations are of constant coefficients, and the corresponding Frobenius integrable ordinary differential equations possess higher-order nonlinearity. The proposed method can be also easily extended to the study of partial differential equations with variable coefficients.
