Abstract

The aim of this paper is to give simple proofs for Jeurnink's characterizations of preregular maps in terms of θ-maps acting between Banach lattices. For Banach lattices E and F, we achieve our goal by considering the space (E,F) of all those linear maps T : E → F for which there exists a constant K such that for all finite sequences . We show that, if (E,F), and the spaces (E,F) of θ-map and (E,F) of preregular maps are respectively endowed with their canonical norms, then they are identical Banach spaces.
