Abstract

Recently it was introduced the so-called Bishop-Phelps-Bollob{\'a}s property for positive operators between Banach lattices. In this paper we prove that the pair (C0(L),Y)(C_0(L), Y) has the Bishop-Phelps--Bollob{\'a}s property for positive operators, for any locally compact Hausdorff topological space LL, whenever YY is a uniformly monotone Banach lattice with a weak unit. In case that the space C0(L)C_0(L) is separable, the same statement holds for any uniformly monotone Banach lattice Y.Y . We also show the following partial converse of the main result. In case that YY is a strictly monotone Banach lattice, LL is a locally compact Hausdorff topological space that contains at least two elements and the pair (C0(L),Y)(C_0(L), Y ) has the Bishop-Phelps--Bollob{\'a}s property for positive operators then YY is uniformly monotone.
