本文研究了二元单未知函数的隐式二阶偏微分方程。特别地,利用微分系统理论,我们给出了具有某种奇异性的偏微分方程的几何特征。此外,我们提供了一个新的接触变换下的偏微分方程的不变量。
In the present paper, we study implicit second-order PDEs (i.e. partial differential equations) of single type for one unknown function of two variables. In particular, by using the theory of differential systems, we give a geometric characterization of PDEs which have a certain singularity. Moreover, we provide a new invariant of PDEs under contact transformations.
