Fractional -calculus
extends fractional calculus and q-calculus
by defining noninteger-order versions of the q-derivative
and q-integral. It includes
-analogues of the Riemann-Liouville
fractional derivative and Caputo fractional
derivative and the corresponding fractional
-difference equations.
As in ordinary fractional calculus, several conventions are used, including left- and right-sided operators,
forms based on the Riemann-Liouville
fractional derivative or Caputo fractional
derivative, and delta and nabla operators on geometric
-time
scales. The resulting kernels are expressed using the q-gamma
function and q-factorials (Atici and Eloe
2007, Annaby and Mansour 2012).
