What's difference between 'functional' and 'function'?
I think this definition is also somewhere in Lang's Linear Algebra. |

On degenerate integrable hamiltonian systems
Dear Daniele Sepe, thanks for your reference. In this paper the integrability condition of Mischenko and Fomenko is interpreted as sufficient for the existence of an isotropic and symplectically complete fibration (FISC after Dazord and Delzant) and hence of generalized action-angle coordinates. I learn also that the first use of the notion of FISC in concrete examples of mechanical interest is the book Nonlinear Poisson Bracket of Maslov and Karasev, and the other paper of Fassò on Euler-Poinsot that you cite. Thank you. |

On degenerate integrable hamiltonian systems
Dear jvkersch, thank you for the reference. Even if in this book there is no mention of degenerate (or super, non commutative) integrability, the detailed analysis of the topology of the momentum map for many classical ham. systems ( Euler top, kepler problem, harmonic oscillator,...; that, by the way, are superintegrable) should permit to recognize the existence of generalized action-angle coordinates at least on a open subset of the phase space. |

History of Gauss' Law
The eighth entry in its bibliography is to the paper of 1813 by Gauss. |

Dear Michael Spivak, you could give a look at this paper of Viktor Katz on the subject, I hope it is useful to you.ingelec.uns.edu.ar/asnl/Materiales/Cap03Extras/Stokes-Katz.pdf |
