开集上线性无关的一组1-形式,若满足本定理的条件中的任意一条,则称其为完全可积的(completely integrable)。消去这些的分布由方程给出,通常写成一个方程组的普法夫方程组(Pfaffian system)

A system of linearly independent 1-forms on an open set , satisfying any of the conditions of this theorem is said to be completely integrable . The equations defining the distribution that annihilates these is given by the equations , often written as a Pfaffian system of equations
