Controllability of neutral functional differential systems in abstract space. (English) Zbl 1175.93029
Summary: By using fractional power of operators and Sadovskii fixed point theorem, we study the controllability and the local controllability of abstract neutral functional differential systems with unbounded delay. As application, an example is provided to illustrate the obtained results.
