A positive integer N is perfect when the sum of all of its positive divisors is exactly twice the number itself:
Every known perfect number is even. Whether an odd perfect number exists remains an open problem. Any hypothetical odd perfect number, however, must satisfy strong restrictions on its prime-factor structure. In particular, it must have the Euler form
where q is the distinguished prime occurring to an odd exponent, while all remaining prime exponents are even.
Let
Since the divisor-sum function is multiplicative over coprime prime-power components, the perfect-number condition may be written as an exact global balance:
The structure is not determined only by this final balance. If a prime-power component
is present, then the prime divisors of
may force additional prime factors to occur in the hypothetical perfect-number structure. Those factors generate further divisor-sum relations, producing a network of structural implications:
The CJM reinterpretation therefore treats a hypothetical odd perfect number not primarily as an integer to be scanned, but as a globally consistent factor-implication structure whose local prime-power components must collectively preserve the exact divisor balance.
The purpose of the encoding is not to reproduce integer multiplication, exponentiation, or divisor-sum calculation inside a Boolean circuit. Those arithmetic relations are evaluated at the native number-theoretic level. The SAT representation instead encodes the logical implications and exclusions produced by those relations.
Consider a finite structural domain containing a finite set of candidate primes, allowed exponent states, and a finite factor-chain depth. Let
and let Yp indicate that the prime p occurs somewhere in the candidate factor structure. The finite encoding is summarized by six principal constraint families:
A typical factor-chain implication may therefore take the schematic form
The resulting implication and exclusion network forms a finite Boolean formula Φ, which is expressed as SAT and normalized through the common CJM 3SAT gate.
Thus, the arithmetic is not Booleanized merely for the sake of conversion. Number theory supplies the structural relations; SAT and 3SAT provide the common logical interface through which those relations are presented to CJM.
Classical factor-chain methods already exploit these implications by extending assumed prime-power structures, forcing additional factors, and eliminating branches when they produce arithmetic contradictions. Such pruning is not proposed here as a CJM innovation.
The distinction proposed by CJM concerns the mechanism of judgment. Conventional factor-chain reasoning develops the implication structure through successive branches:
CJM instead asks whether the resulting finite implication structure, once normalized as 3SAT, could be presented as a whole to a physical admissibility mechanism:
If such a mechanism exists, the proposed difference would not lie in discovering new divisor identities or new pruning rules, but in applying a different physical mode of discrimination to the already normalized global structure. This remains a hypothesis until the physical CJM mechanism is explicitly realized and experimentally demonstrated.
Let ℳd denote the finite model space that remains structurally consistent after factor implications and exclusions have been expanded to a chosen depth d. A simple structural observable may be written schematically as
Increasing factor-chain depth or adding stronger structural restrictions generally reduces the surviving model space. The relevant question is not whether individual branches disappear, but whether the global family undergoes a sharp and reproducible reorganization as structural constraints accumulate.
A candidate Changbal Region would therefore correspond to a regime in which the population or organization of structurally consistent factor models changes nonlinearly. Such behavior would not itself prove or disprove the existence of an odd perfect number; it would characterize the finite admissibility landscape presented to CJM.
The present formulation deliberately avoids converting the basic arithmetic operations of the odd perfect number problem into large Boolean arithmetic circuits. Existing number-theoretic methods already evaluate divisor sums, prime factorizations, congruence conditions, and abundancy relations far more naturally in their native arithmetic form. Reproducing those computations gate by gate in SAT would add complexity without supplying a corresponding structural advantage.
The 3SAT stage therefore begins only after number theory has produced the relevant factor implications and exclusions. In this sense, 3SAT serves as a common normalization interface rather than as a replacement for arithmetic. Classical factor-chain methods and CJM may use the same underlying structural information; the unresolved distinction is whether physical CJM can judge the complete normalized structure globally without reproducing an equivalent branch-by-branch computational process.
This sketch does not prove or disprove the existence of an odd perfect number, introduce a new divisor-theoretic restriction, or claim that SAT or 3SAT is more efficient than established arithmetic and factor-chain methods.
The finite Boolean structure also represents only the chosen prime domain, exponent states, factor-chain depth, and included number-theoretic constraints. An UNSAT result therefore excludes only that finite structural domain; it does not establish that no odd perfect number exists. Conversely, a SAT result indicates only that the encoded necessary conditions remain mutually consistent and does not imply that an actual odd perfect number has been found.
Nor does this sketch demonstrate that physical CJM can perform global admissibility discrimination without reproducing an equivalent conventional search. Its purpose is narrower: to preserve the native factor structure of the odd perfect number problem, translate its finite implication network into the common 3SAT interface, and isolate the subsequent CJM question immediately before physical evaluation.
