Abstract:

In this paper, We discuss Riemann-Liouville fractional evolution differential systems in Banach spaces. Firstly, the existence of $C_{1-\alpha}$-mild solutions for the Riemann-Liouville fractional evolution differential equations are established in Banach spaces. Secondly, we make some general assumptions to guarantee the approximate controllability of the associated Riemann-Liouville fractional evolution systems is also formulated and proved. In the end, an example is given to illustrate our main results.

Key words: Riemann-Liouville fractional evolution differential systems, $C_{1-\alpha}$-mild solutions, existence, approximate controllability
