theorem
EulerPacketBaseScales.first_stage_coefficient_error_tendsto_zero
(T D N b : ℝ)
(hD : 1000 ≤ D)
(hb : 0 < b)
:
The first normal stage has h=x₀^1000, hence epsilon of order
x₀^-500; its complete coefficient error beats x₀^-10 Θ^-60.
theorem
EulerPacketBaseScales.second_stage_shear_error_tendsto_zero
(T b : ℝ)
(hb : 0 < b)
(A : ℕ)
:
At the special second stage the older gradient is polynomial in the base scale, while the new inverse shear is exponentially small.
theorem
EulerPacketBaseScales.base_horizon_tendsto_zero
(J : ℝ)
:
Filter.Tendsto (fun (x : ℝ) => 6 * J ^ 2 * x ^ (2 - 1000 / 2)) Filter.atTop (nhds 0)
The exact base horizon 6 J² x₀^(2-1000/2) tends to zero.
