Exponent budget for the tiny source contract #

δ N_* ≥ 10 + q β: the N_* is large enough to absorb every negative power of ε_{m-1} (the lower bound ε_m ≳ ε_{m-1}^q and the analytic-radius losses) occurring in the estimate of e.monster.est.tiny (enhance.tex 7848-7930).

theorem AVenhance.Infra.Section5.Contracts.sc_budget_core {q δ N : ℝ} (hq : 1 < q) (hδ : δ = (q - 1) ^ 2 / (4 * (q + 1) * (4 * q - 1))) (hN : 500 / δ + 128 * q ^ 2 * (q - 1) ≤ N) :
10 + 4 * q / 3 ≤ δ * N

Abstract-real core, in terms of q > 1 only: if δ = (q-1)²/(4(q+1)(4q-1)) and N ≥ 500/δ + 128 q²(q-1) then 10 + 4q/3 ≤ δ N.

theorem AVenhance.Infra.Section5.Contracts.sc_delta_Nstar_budget {β : ℝ} (hβ : 1 < β) (hβ' : β < 4 / 3) :
10 + q β * β ≤ delta β * ↑(Nstar β)

Exponent budget: 10 + q β ≤ δ N_*.
