Limits for an actual family of constructed bodies

The family is indexed by rank j + 1, so every individual body has a positive dimension and positive primal entropy. Its defining properties concern the literal covering numbers; the limit arguments do not replace them by new abstract quantities.

    Source documentation

    The actual dimensions tend to infinity; no monotonicity is required.

        (P : ∀ j : ℕ, EntropyPair a (j + 1) ((j + 1 : ℕ) : ℝ)) :

    Source documentation

    The quotient here is the actual dual entropy divided by the actual, strictly positive primal entropy at every index.
