Approximate controllability of Riemann-Liouville fractional evolution equations with integral contractor assumption
Shouguo Zhu,Zhenbin Fan and Gang Li
Keywords:Approximate controllability, Riemann-Liouville fractional derivatives, resolvent, regular integral contractor.
      We propose and investigate an evolution system with a Riemann-Liouville fractional derivative. With the aid of a resolvent method, we formulate a suitable notion of solutions to this system and demonstrate the corresponding existence and uniqueness of solutions under a regular integral contractor condition. Furthermore, by applying a space decomposition technique, we exhibit the approximate controllability result of the system. This paper closes with a simple example, which confirms our analytical findings.
