Abstract: In this paper, we prove that the generator of any bounded analytic semigroup in (θ,1)-type real interpolation of its domain and underlying Banach space has maximal L1-regularity, using a duality argument combined with the result of maximal continuous regularity. As an application, we consider maximal L1-regularity of the Dirichlet-Laplacian and the Stokes operator in inhomogeneous Bsq,1-type Besov spaces on domains of Rn, n2.

Key words: Maximal L1-regularity, sectorial operator, Stokes operator
