%0 Journal Article %T Response Solutions for a Singularly Perturbed System Involving Reflection of the Argument %A Li %A Qingling %A Zhang %A Shufang %A Zhang %A Xinli %A Zhu %A Shanliang %J - %D 2020 %R https://doi.org/10.1155/2020/6738247 %X In this paper, the existence and uniqueness of response solutions, which has the same frequency with the nonlinear terms, are investigated for a quasiperiodic singularly perturbed system involving reflection of the argument. Firstly, we prove that all quasiperiodic functions with the frequency form a Banach space. Then, we obtain the existence and uniqueness of quasiperiodic solutions by means of the fixed-point methods and the -property of quasiperiodic functions %U https://www.hindawi.com/journals/amp/2020/6738247/
