Geometric characterization of preduals of injective Banach lattices

Abstract

The paper deals with the study of Banach spaces whose duals are injective Banach lattices. Davies in 1967 proved that an ordered Banach space is an L1-predual space if and only if it is a simplex space. In 2007 Duan and Lin proved that a real Banach space is an L1-predual space if and only if its every four-point subset is centerable. We prove the counterparts of these remarkable results for injectives by the new machinery of Boolean valued transfer from L1-spaces to injective Banach lattices.
