p.
The classical KAM theorem solves the small-divisor problem when small perturbations are introduced to this function. The partial time derivative of a probability distribution p is given by the Poisson bracket of this function with p. The Legendre transform which transforms from generalized velocity coordinates to conjugate momenta produces it from the Lagrangian. The time- independent Schrödinger equation is an eigenvalue equation for, for ten points, what operator, the observable corresponding to the total energy?
