Notes
- 1.
Some other time we will need the following basic fact: contractive perturbations of the identity in \(\mathbb{R}^{n}\) are bi-Lipschitz homeomorphisms.
- 2.
Compared with the three operations involving generating functions that left unchanged the generated Lagrangian submanifold, see Sect. 7.2.1.
