Salem, Hussein A. H.; El-Sayed, A. M. A.; Moustafa, O. L. A note on the fractional calculus in Banach spaces. (English) Zbl 1086.45004 Stud. Sci. Math. Hung. 42, No. 2, 115-130 (2005). Let \(E\) be a Banach space (in some of the results additionally required to be reflexive). The authors consider the abstract fractional integral equation \(x(t) = g(t) + \lambda I^\alpha [f(\cdot, x(\cdot))](t)\) with unknown solution \(x:[0,1] \to E\) and given functions \(f : [0,1]\times E \to E\) and \(g :[0,1] \to E\). Existence results for the solution of this equation are given, where \(I^\alpha\) is the fractional integral of weak Riemann, Pettis or Bochner type of order \(\alpha > 0\).
