Fractional calculus in Physics?

  1. Apr 23, 2003 #1
    Has any menaing the use of fractional calculus in..physics?.i have used it several time to quantizy non-polynomial hamiltonians in quantum mechanics...(such us H=p**e e not an integer).but does the fractional calculus have a meaning or utility in physics?..to cancel infinities to calculate perturbation corrections or all that...

    Do you mean 'variational calculus?' I'm afraid I've never heard the term 'fractional calculus.'

    Also, I've never once seen a polynomial Hamiltonian. ;)

    Sorry..perhaps it was my bad english..when i meant "polynomial" i mean hamiltonians of the form....

    H**2=Px**2+Py**2+.. or H=Px**2+Py**2..that is the variables E and P,s appear in that way (the powers are always integer).

    By fractional calculus it is mean that instead of using the operator (d/dx)**n being n and integer n can be real or even complex you can take a look about it in www.mathworld.com
