Iterated Carleson sums for a finite laminar family

The family is indexed by occurrences, so equal geometric intervals from different bins retain their multiplicity. Iterating the actual Carleson mass bound controls every non-strict nested-chain sum.

    Source documentation

    Monotonicity of the scale rank turns every nonempty intersection into an actual nested chain; empty intersections contribute zero.
