Order-Theoretic Lens
For mathematicians, theoretical computer scientists, and category/order theory readers.
This entry route explores how Cohesion Dynamics substrate behaviour maps onto order-theoretic structures such as refinement, closure, partial joins, and formal classification.
Overview
If you’re comfortable with order theory, domain theory, or categorical approaches to computation and information, this lens provides a mathematically rigorous entry point to Cohesion Dynamics.
Key Order-Theoretic Structures in CD
CD’s substrate mechanics and cohesion behaviour naturally express themselves in order-theoretic terms:
- Refinement orderings on informational structures
- Partial joins and closure operations
- Lattice-like structures emerging from coherence constraints
- Fixed points and attractors in substrate evolution
- Capability hierarchies classifying informational continua
Core Order-Theoretic Concepts
Refinement
In CD, informational structures can be refined — one structure is a refinement of another if it preserves all properties while adding specificity or constraint.
Refinement defines a partial order on the space of structures, and this order governs:
- Constructor emergence (more refined substrates support more constructor types)
- Quantum structure (refinement of admissibility constraints)
- Phase transitions (discrete jumps in refinement orderings)
Closure and Coherence
Coherence in CD can be understood as a closure operation:
- Given a set of informational constraints, their closure is the minimal coherent structure satisfying them
- Closure operations exhibit idempotence, monotonicity, and extensivity
- Failures of closure correspond to branching or divergence
Partial Orders on Continua
CD classifies informational continua by what they can stably support, yielding a capability-based partial order:
- Base continua (minimal persistence)
- Constructor-capable continua
- Quantum-capable continua
This classification isn’t arbitrary — it’s derived from eliminative empirical results (E-series).

- B-series: Structural Consequences — Derived structural theorems
Key Insights for Order Theorists
CD is Not Just Applied Order Theory
While CD uses order-theoretic structures heavily, it’s not merely an application of existing order theory. Instead:
- Order-theoretic structures emerge from substrate mechanics
- The framework derives which orderings are physically relevant
- Empirical constraints (E-series) narrow the space of viable orderings
Refinement ≠ Logical Implication
Refinement in CD isn’t purely logical:
- It has physical content — refined substrates behave differently
- Refinement jumps correspond to phase transitions
- Not all refinements are physically realisable
Fixed Points and Constructors
Constructors in CD are characterised as fixed points of substrate evolution:
- A constructor is a structure that, when applied, reproduces itself
- Substrate conditions determine which fixed points exist
- Constructor emergence is necessary, not assumed
Connections to Existing Work
Domain Theory
CD’s substrate has connections to domain theory:
- Information orderings resemble Scott domains
- Coherence constraints are like directed completeness
- But CD adds physical constraints not present in pure domain theory
Category Theory
While not primarily categorical, CD has categorical structure:
- Morphisms between informational structures
- Functorial relationships between substrate layers
- Adjunctions between construction and refinement
Lattice Theory
Cohesion constraints form lattice-like structures:
- Joins correspond to reconciliation
- Meets correspond to constraint intersection
- But not all reconciliations have well-defined joins (hence branching)
