The (a+ib) derivative of f(x)

  1. Oct 8, 2011 #1
    Is there anyway to calculate successive derivatives of the form

    [tex]\frac{{d}^{a+ib}}{d{x}^{a+ib}} [f(x)] [/tex]

    If we are assuming [itex]f:\mathbb{R}\rightarrow \mathbb{R}[/itex] this is precisely the http://en.wikipedia.org/wiki/Riemann%E2%80%93Liouville_integral" [Broken] derivative.

    Find a book on fractional calculus and the most of the result transfer to complex orders directly.
