Abstract. We study questions related to asymptotic almost periodicity of solutions of the linear convolution equation (») p » x = f. Here p is a complex measure, and x and / are bounded functions. Basically we are interested in conditions which imply that bounded solutions of (*) are asymptotically almost periodic. In particular, we show that a certain necessary condition on / for this to happen is also sufficient, thereby strengthening earlier results. We also include a result on existence of bounded solutions, and indicate a generalization to a distribution equation.
