Modeling with fractional difference equations

open access: yesJournal of Mathematical Analysis and Applications, 2010
A fractional sum of a function \(f\) is introduced as \[ \Delta _{a}^{-\alpha}f(t)=\frac{1}{\Gamma (\alpha )}\sum_{s=a}^{t-\alpha }(t-s-1)^{(\alpha -1)}f(s), \] where \(a\in R,\) \(\alpha >0\), \(x^{(\alpha )}=\Gamma (x+1)/\Gamma (x-\alpha +1),\) \(f\) is defined for \(s=a\;(\text{mod }1),\) and \(\Delta _{a}^{-\alpha }f\) is defined for \(t=a+\alpha \;
