Abstract
Pre-Riesz spaces are ordered vector spaces which can be order densely embedded into vector lattices, their so-called vector lattice covers. Given a vector lattice cover for a pre-Riesz space , we address the question how to find vector lattice covers for subspaces of , such as ideals and bands. We provide conditions such that for a directed ideal in its smallest extension ideal in is a vector lattice cover. We show a criterion for bands in and their extension bands in as well. Moreover, we state properties of ideals and bands in which are generated by sets, and of their extensions in .
