摘要: This is a summary of the main results contained in forthcoming joint paper with S. Be-nenti and G. Rastelli, where we revisit theory separation variables theHamilton–Jacobi equation fixed value energy. We extend classical Levi-Civita conditions by using Lagrangian multipliers. By applying general to thecase natural Hamiltonians find generalizing those St¨ackel.
