This textbook provides a self-contained introduction to a developing area at the intersection of ring theory and order theory. Beginning with foundational concepts and results, it explores the connections between infinite primes, maximal partial orders, symmetric partial orders, and directed orders in fields, integral domains, and more general commutative rings. Topics include embedding theorems, Archimedean and strong Archimedean orders, partial orders on complex numbers and quaternions, rings with negative squares, Dedekind σ-complete partially ordered rings, O*-fields, and L*-rings. Each chapter concludes with exercises that reinforce the theory, illustrate key constructions, and highlight open questions for further investigation. Written for graduate students and researchers with a background in abstract algebra, this text combines foundational material and modern developments, offering an accessible entry point into this area of research.
