Abstract

The general ideas introduced in [8] are adopted in order to investigate the quasi cones and the cones of a ring. Using the finite extension property for cones, we answer the question, when a partial order in a partially ordered ring has a compatible linear extension (equivalently, when the positive cone is contained in a full cone). It turns out, that if there is no such extension, then it is caused by a finite system of polynomial like equations satisfied by some elements of a certain finite subset of the ring and some positive elements. As a consequence, we prove that a partial order can be linearly extended if and only if it can be linearly extended on every finitely generated subring.
