论文摘要
使用移动框架的方法，我们分析了三维仿射几何形状中差分不变的代数。对于椭圆形，双曲线和抛物线点，我们表明，如果差异不变的代数是非平凡的，那么它通常由单个不变性生成。
Using the method of moving frames we analyze the algebra of differential invariants for surfaces in three-dimensional affine geometry. For elliptic, hyperbolic, and parabolic points, we show that if the algebra of differential invariants is non-trivial, then it is generically generated by a single invariant.
