Lattice-Ordered Matrix Rings Over Totally Ordered Rings

Order, 2013
In this article, the authors generalize the results on matrix \(l\)-algebras over totally ordered fields to matrix \(l\)-algebras over totally ordered integral domains. The authors derive necessary and sufficient conditions that ensure the entrywise lattice order on \(M_n(R)\), where \(R\) is an integral domain, is the unique lattice order to make it ...

Completions of Convexly Ordered Valuation Rings

Mathematical Logic Quarterly, 1994
AbstractWe prove that every convexly ordered valuation ring has a unique completion as a uniform space, which furthermore is a convexly ordered valuation ring. In addition, we give a model theoretic characterisation of complete convexly ordered valuation rings, and give a necessary and sufficient condition for the completion of a convexly ordered ...

Orders on computable rings

Mathematical Logic Quarterly, 2020
AbstractThe Artin‐Schreier theorem says that every formally real field has orders. Friedman, Simpson and Smith showed in [6] that the Artin‐Schreier theorem is equivalent to over . We first prove that the generalization of the Artin‐Schreier theorem to noncommutative rings is equivalent to over . In the theory of orderings on rings, following an idea

Rings of order p3

Siberian Mathematical Journal, 1982
The present paper presents a classification of the rings of order p3 which differs from the ciassifications given in (13) and (14). We show that there are 52 nonisomorphic rings for p = 2 and 3p + 50 for p ~ 2. The same result was obtained in (14) by accident, since (14) contains some "errors of signs." At the same time we clarify some errors contained
