Epimorphic extensions and Prüfer extensions of partially ordered rings
This paper contributes to the investigation of epimorphisms in the category of reduced partially ordered rings (porings). Two main questions are considered: (1) Does the set of isomorphism classes of a given poring have a largest element (an epimorphic hull)? (2) Given an epimorphic extension, or even a Prüfer extension, \(f:A\to B\) of porings: How closely are \(A\) and \(B\) related to each other?
