We prove an ‘h-principle without pre-conditions’ for the elimination of tangencies of a Lagrangian submanifold with respect to a Lagrangian distribution. The main result states that such tangencies can always be completely removed at the cost of allowing the Lagrangian to develop certain non-smooth points, called Lagrangian ridges, modeled on the corner together with its products and stabilizations. This result plays an essential role in the arborealization program.

拉格朗日脊地貌
我们证明了一个“无先决条件的 h 原理”,用于消除拉格朗日子流形相对于拉格朗日分布的切线。主要结果表明,这种切线总是可以完全消除,但代价是允许拉格朗日函数发展某些非光滑点,称为拉格朗日脊,以拐角为模型连同其产品和稳定剂。这一结果在树栖计划中起着至关重要的作用。
