| 1. Domain | 1.1 Scope of the Domain | Boundaries | The range of phenomena the science includes and excludes. | Studies algebraic structures with two operations—addition and multiplication—satisfying distributivity, additive associativity/commutativity, and the existence of additive identity/inverses. Includes commutative rings, noncommutative rings, integral domains, ideals, factorization, homomorphisms, modules, polynomial rings, and matrix rings. Excludes algebraic systems lacking stable two-operation structure (e.g., quasigroups, semigroups without addition). |
| | Scale | The spatial, temporal, or organizational level at which the science operates (e.g., quantum, cellular, social, cosmic). | Operates at algebraic, arithmetic, and structural scales: finite rings, infinite rings, local/global ring properties, factorization patterns, ideal lattices, and module-theoretic behavior. |
| 1.2 Ontological Commitments | Entities | The kinds of things assumed to exist within the domain (particles, organisms, agents, fields, etc.). | Ring elements, additive identity (0), multiplicative identity (1) when present, ideals, prime ideals, maximal ideals, homomorphisms, quotient rings, polynomial elements, matrices, units, zero divisors. |
| | Properties | The fundamental attributes these entities possess (mass, charge, genotype, preference, etc.). | Additive commutativity, associativity, distributivity, presence/absence of multiplicative identity, commutativity of multiplication (in commutative rings), presence of units, factorization properties (UFD, PID), characteristic, nilpotence, integrality. |
| | Categories | The basic ontological types used to classify domain elements (substances, processes, relations, structures). | Commutative rings, noncommutative rings, integral domains, fields (as special rings), PIDs, UFDs, Noetherian rings, Artinian rings, matrix rings, polynomial rings, local rings, valuation rings, coordinate rings of algebraic varieties. |
| 1.3 State-Variables | Variables | The measurable or definable properties that describe system conditions. | Selected ideal, chosen factorization, current ring element, degree of polynomial, order of nilpotence, determinant/trace (for matrices), characteristic, localization choice, maximal/prime spectrum element. |

| 1.4 Admissible Idealizations | Simplifications | Conceptual reductions used to make the domain tractable (point masses, rational agents, perfect gases). | Restricting attention to commutative rings; focusing on rings with unity; using principal ideals instead of arbitrary ideals; simplifying to finitely generated ideals; ignoring topological or geometric structure when treating coordinate rings purely algebraically. |
| | Validity Conditions | The limits and contexts in which idealizations hold or break down. | Breakdown occurs in non-Noetherian rings (loss of finiteness properties), highly pathological ideals, noncommutative rings where standard intuition fails, rings without identity (different homomorphism behavior), or when geometric/topological structure is essential. |
| 1.5 Domain Assumptions | Structural Assumptions | Background ontological stances such as determinism, continuity, randomness, discreteness. | Ring axioms always hold; distributivity links addition and multiplication; ideals behave consistently under homomorphisms; quotient constructions are well-defined; factorization interacts predictably with ideal structure; localization preserves algebraic coherence. |
| | Implicit Commitments | Unstated but necessary assumptions that shape the field’s conceptual structure. | Assumes associativity of multiplication (unless explicitly in non-associative settings); assumes ideals capture structural information; assumes generators/relations adequately describe ring structure; assumes polynomial rings behave generically across contexts. |
| 1.6 Internal Coherence Requirements | Consistency | The demand that domain concepts do not contradict one another. | Addition and multiplication must not contradict ring axioms; ideal operations must respect ring structure; homomorphisms must preserve both operations; quotient rings must satisfy ring axioms; factorization must align with ideal structure. |
