Abstract: | The linear non-autonomous evolution equation , with the initial datum u(0) = x, in the space C(0, T], E), where E is a Banach space and {A(t)} is a family of infinitesimal generators of bounded analytic semigroups is considered; the domains D(A(t)) are supposed constant in t and possibly not dense in E. Maximal regularity of the strict and classical solutions, i.e., regularity of u′ and A(·)u(·) with values in the interpolation spaces DA(0)(θ, ∞) and DA(0)(θ) between D(A(0)) and E, is studied. A characterization of such spaces in a concrete case is also given. |
