Amplifying the positive centered-energy expansion by extensions

  1. theorem OAI.Ostmann.subset_energy_amplification line 10
  2. theorem OAI.Ostmann.prime_subset_energy_budget line 44

    Source documentation

    Once the concrete extension weights are supplied, the actual centered subset energies inherit the classical additive-sieve budget.
