In this paper, for the bounded solution of the non-densely defined non-autonomous evolution equation, we present the condition for asymptotic periodicity by using the circular spectral theory of functions on the half line and the extrapolation theory of non-densely defined evolution equation.
Keywords: Circular spectrum, asymptotic periodic solution, evolution semigroup, Massera theorem
