This book deals with the controllability and periodicity results of the neutral impulsive evolution system. Also the uniqueness of asymptotically almost periodic solutions for the governing control system has been studied. The required controllability results are executed through the analytic semigroup theory and Sadovskii fixed point theorem approach. Moreover, examples are provided to understand the theory as well, These results are mostly applied to economics, mechanics, electronics, medicine and biology, pharmacokinetics, orbital transfer of satellite, ecosystems management.
