Uniform finite-axis rescaled field bounds on compact time intervals #

The hbdd hypothesis shape (uniform boundedness on rectangles of bounded time) for the finite-axis rescaled radial and vertical fields V_n, W_n (and the swirl source S_n) of eq:aniso:zoom:fields, the companion boundedness input that an eventual Arzelà–Ascoli extraction of (V_n, W_n) in C¹_loc (eq:aniso:zoom:finite:compactness) needs alongside the equicontinuity modulus.

∃ (M : ℝ), ∀ (lam : ℝ), 0 < lam → ∀ (p : (ℝ × ℝ) × ℝ), zoomPoint lam h zc p ∈ unitCylinder → p.2 ∈ J → |zoomV lam h zc u p| ≤ M

For every compact set J ⊆ (-∞, -1] and every C ≥ 0, the rescaled radial field zoomV is uniformly bounded on {zoomPoint … ∈ unitCylinder} × J by a constant M depending only on C, J, and the exponent -(1/2).

For every compact set J ⊆ (-∞, -1] and every C ≥ 0, the sum |zoomW| + |zoomS| is uniformly bounded on {zoomPoint … ∈ unitCylinder} × J by a constant M depending only on C, J, h, and the exponent -(1/2) - h.

Combined uniform bound for |zoomV| + |zoomW| + |zoomS| on {zoomPoint … ∈ unitCylinder} × J. Follows from the two separate bounds above via additivity.
