LTF Papers

Defines the structural basis for cross‑layer transformation and the operators, mechanisms, and relationships that make it possible.

Defines abstraction as the upward operator that lifts a coherent structure into a higher layer while preserving invariants and coherence.

Describes the three‑stage mechanism—isolation, lifting, activation—that performs the upward transition.

Defines compression as the downward operator that restores compatibility with lower‑layer constraints while preserving identity.

Describes the three‑stage mechanism—contraction, descent, reintegration—that performs the downward transition.

Defines duality as the structural relationship that coordinates the two operators and mechanisms while preserving identity and coherence.
