Asymptotically Almost Periodic Solutions of Inhomogeneous Cauchy Problems on The Half‐Line

Asymptotically Almost Periodic Solutions of Inhomogeneous Cauchy Problems on The Half‐Line Let u be a bounded, uniformly continuous, mild solution of an inhomogeneous Cauchy problem on R+: u′(t)+Au(t)+φ(t)(t⩾0). Suppose that u has uniformly convergent means, σ(A)∩iR is countable, and φ is asymptotically almost periodic. Then u is asymptotically almost periodic.

Abstract

Let u be a bounded, uniformly continuous, mild solution of an inhomogeneous Cauchy problem on R+: u′(t)+Au(t)+φ(t)(t⩾0). Suppose that u has uniformly convergent means, σ(A)∩iR is countable, and φ is asymptotically almost periodic. Then u is asymptotically almost periodic. Related results have been obtained by Ruess and Vũ, and by Basit, using different methods. A direct proof is given of a Tauberian theorem of Batty, van Neerven and Räbiger, and applications to Volterra equations are discussed. 1991 Mathematics Subject Classification 34C28, 44A10, 47D03.
