Distinguished completion of a direct product of lattice ordered groups. (English) Zbl 1079.06505
Summary: In the present paper we prove that if a lattice ordered group $$G$$ is a direct product of lattice ordered groups $$G_i$$ $$(i\in I)$$, then $$E(G)$$ is a direct product of the lattice ordered groups $$E(G_i)$$.
From this we obtain a generalization of a result of R. N. Ball [Algebra Univers. 35, 85-112 (1996; Zbl 0842.06012)].
