The output of the concrete counterexample construction

Every field below concerns the actual finite-dimensional body, its literal cube and polar, or their covering numbers. The construction theorem supplies this record from only the numerical inputs a, r, and B.

  1. def OAI.MetricEntropyDuality.entropyRatio line 23

    Source documentation

    The actual quotient of dual covering entropy by primal covering entropy.

  2. def OAI.MetricEntropyDuality.entropyBudget line 29

    Source documentation

    The scalar upper bound, with radius and pivot count fixed by a alone.

    Source documentation

    A constructed body with its actual geometric and entropy properties. No matrix, compression theorem, or abstract entropy function is a field.
