Four Structural Invariants (REA)

Definition

The four mathematical conditions that must hold for a capital system to be regenerative: R (recycling rate), γ (capability return), Δ (decoupling operator), and Λ (alignment operator). Together they define the regenerative criterion.

Formula

Example

Traditional grants fail on R (no recycling). Debt fails on γ (extracts rather than generates). Equity fails on Δ (coupled to market cycles). Only regenerative capital satisfies all four.
