summary
plain-language theorem explainer
Recognition Science interprets phase transitions as bifurcations in the J-cost landscape through this enumerated summary. Thermodynamic derivations from recognition costs would cite the list when classifying first-order jumps versus second-order mergers of minima. The definition is a direct list construction with no lemmas or computation.
Claim. Phases correspond to local minima of the J-cost function, first-order transitions are jumps between separated minima, second-order transitions occur when minima merge with diverging fluctuations, the critical point marks a topology change in the landscape, and nucleation is thermal crossing of barriers.
background
The J-cost function is the derived cost of a multiplicative recognizer's comparator on positive ratios, as defined in MultiplicativeRecognizerL4.cost, and equals the recognition cost of any event in ObserverForcing.cost. Phase is the 8-tick cycle space Fin 8 from both ChurchTuringPhysicsStructure and EightTick, with phase 0 marking the start of LOCK. The module sets the local theoretical setting as THERMO-006, deriving phase transitions from J-cost bifurcations where the landscape has multiple local minima that merge or split as parameters change.
proof idea
This is a direct definition that enumerates the five key mappings from the J-cost landscape to physical transition types. No lemmas are applied and the body is a literal list of strings.
why it matters
The definition supplies the high-level mapping for the paper proposition on phase transitions as information-theoretic bifurcations. It grounds thermodynamic behavior in the eight-tick octave and J-uniqueness from the forcing chain, connecting the 8-tick phase space to the cost minima that drive transitions. It touches the open question of extracting critical exponents from the phi-ladder.
