## Nonstandard hulls of ordered vector spaces.(English)Zbl 1348.46075

The authors extend the technique of nonstandard hulls from vector lattices to ordered vector spaces. They introduce some external subspaces that generalize the subspaces of order-finite and order-infinitesimal elements and apply these concepts to studying the properties of nonstandard hulls, order convergence, Dedekind completion, etc. Some applications are also given to normed ordered vector spaces.
