摘要: This paper is mainly concerned with the $S$-asymptotically Bloch type periodicity. Firstly, we introduce a new notion of $S$-asymptotically Bloch type periodic functions, which can be seen as a generalization of concepts of $S$-asymptotically $\omega$-periodic functions and $S$-asymptotically $\omega$-anti-periodic functions. Secondly, we establish some fundamental properties on $S$-asymptotically Bloch type periodic functions. Finally, we apply the results obtained to investigate the existence and uniqueness of $S$-asymptotically Bloch type periodic mild solutions to some semi-linear differential equations in Banach spaces.
