“…Veech [48,49] and others ( [3,14,23,25,[34][35][36]45,52] and the references therein). The almost automorphic solutions of differential equations were investigated in a series of recent works, see [5,12,15,21,35,37,45,55] and the references therein. Almost automorphic dynamics is known to be fundamental in almost periodically forced differential equations.…”
