1. Domain of the Collatz Conjecture
The Collatz Conjecture is formally defined only for Positive Integers (ℕ⁺).
Motivation for Strict Positive Integers Domain:
When the Collatz rules (n/2 if even, 3n+1 if odd) are applied to negative integers, the behavior completely changes. Instead of converging to the single 4 → 2 → 1 cycle, negative numbers fall into multiple different cycles.
This total loss of unified convergence makes the original conjecture lose its sense in the negative domain.
Therefore, the extension into negatives naturally creates a separate and independent conjecture called MCVR (Modified Collatz Variant Rule).
This clear separation is essential: solving the classic Collatz Conjecture (positive integers) does not automatically solve the behavior in negative numbers, and vice versa.
4. Collatz Functional Divergence Functions
C.E.-1 (LET1):
\( \bigl(2^{(2k+2)} \bigr) \times (1 + 6i) - 1 = 3 Q_i \)
C.E.-2 (LET2):
\( \bigl(2^{(2l+1)} \bigr) \times (5 + 6j) - 1 = 3 Q_j \)
where \( k, l, i, j = 0,1,2,\dots \)
6. Murgu Collatz Unicity – Second Key of the Framework
Murgu Collatz Unicity is one of the central pillars of the Table2To3 Structure and Coordinate System.
LET1 (1 + 6i) and LET2 (5 + 6j) act as Triads Engines.
• Each LET node has infinitely many upward Collatz connections (inverse direction).
• However, in the downward direction (forward Collatz iteration), every node has exactly one unique connection.
This downward unicity — that each number maps to one and only one successor through the defined functional divergence — is a fundamental characteristic revealed by the Murgu Table2To3 Coordinate System.
This unicity, combined with the LDN closures and the mod-6 partitioning, forms the foundation for the claim of a structured unique solution path toward the 4 → 2 → 1 cycle for all positive integers.
7. MCVR – Modified Collatz Variant Rule (Independent Conjecture)
MCVR manifests in two main aspects:
1. Positive Domain Variant (3x − 1 behavior)
Instead of converging to a single cycle, it produces multiple roots. Examples:
5 → 7
17 → 25 → 37 → 55 → 41 → 61 → 91 → ...
(and several other independent cycles)
2. Negative Domain (Classic Collatz Rules)
The behavior becomes even more fragmented:
(−1)
(−5) → (−7)
(−17) → (−25) → (−37) → (−55) → (−41) → (−61) → (−91) → ...
(and multiple other cycles)
These examples clearly demonstrate that Collatz Conjecture loses its unified sense in the negative domain. The single attractive cycle (4 → 2 → 1) disappears completely.
This fundamental difference justifies treating MCVR as a fully independent conjecture, separate from the classic Collatz Conjecture (which remains strictly defined for positive integers).
