SUMMARY

The discussion centers on the Lagrange-D'Alembert Principle, a critical concept in classical mechanics, and its generalization to mechanics-like ordinary differential equations (ODE) in Banach spaces. The author presents an application involving geodesics in infinite-dimensional manifolds and a random ODE with nonholonomic constraints. Additionally, the author explores the relationship between the Schrödinger equation in quantum mechanics and the Lagrange-D'Alembert principle, referencing two papers available on arXiv.

Here is my paper. A criticism and other comments are welcome.

Abstract: The Lagrange-D'Alembert Principle is one of the fundamental tools of classical mechanics. We generalize this principle to mechanics-like ODE in Banach spaces.
As an application we discuss geodesics in infinite dimensional manifolds and a random ODE with nonholonomic constraint.

Interesting.

In Quantum mechanics, the time evolution given by the Schrödinger equation can be restated as a infinite dimensional (classical) Hamiltonian system (at least for the discrete spectrum case). So I wonder if you could state a Lagrange-D'Alembert principle for QM

I give a review of the above statement in https://arxiv.org/abs/2107.07050
