Abstract
In this paper we give a characterization of σ-order continuity of modular function spaces L% in terms of the existence of best approximants by elements of order closed sublattices of L%. We consider separately the case of Musielak–Orlicz spaces generated by non-σ-finite measures. Such spaces are not modular function spaces and the proofs require somewhat different methods.
