Povzetek:
Partially ordered rings (=porings) are algebraic structures that are used by many mathematicians. They form a category (where the order-preserving homomorphisms serve as maps) with a very rich structure. Model theory provides particularly important tools for the analysis of this category. Reflectors of the category of porings can be described explicitly. They have substantial applications in real algebraic geometry.
