摘要

让 ξ $\xi$ 是一个解析括号生成分布。我们证明，在与 ξ $\xi$ 相切的光滑曲线的胚芽空间中，奇异胚芽的子空间（在控制论的意义上）具有无限的开方维。我们将其形式化为关于切线曲线的有限射流的渐近声明。从这些陈述中，通过格罗莫夫的论证，h $h $ 原则对于横向于 ξ $\xi$ 的映射和浸入是成立的。

Microflexiblity and local integrability of horizontal curves

Let $ξ$ be an analytic bracket-generating distribution. We show that the subspace of germs that are singular (in the sense of control theory) has infinite codimension within the space of germs of smooth curves tangent to $ξ$ . We formalize this as an asymptotic statement about finite jets of tangent curves. This solves, in the analytic setting, a conjecture of Eliashberg and Mishachev regarding an earlier claim by Gromov about the microflexibility of the tangency condition.

From these statements it follows, by an argument due to Gromov, that the $h$ -principle holds for maps and immersions transverse to $ξ$ .
