Λ(T,H) Kernel Equivalences — Zeta Mirror

Kernel-smoothed convolutions of |ζ(½+iT)|² mirror the Riemann Zeta function zeros on the critical line

Λ(T,H) = ∫ |ζ(½+i(T+u))|² · K(u,H) du  /  ∫ K(u,H) du
limH→0⁺ Λ(T,H) = |ζ(½+iT)|² = 0 ⇔ ζ(½+iT) = 0

The 6 Equivalent Kernel Forms (all ≡ sech²):

K₁ sech²(u/H) = 1/cosh²(u/H) Primary form
K₂ 4 / (eu/H + e−u/H Exponential expansion
K₃ d/du[tanh(u/H)] · H Derivative form
K₄ 4e2u/H / (e2u/H + 1)² Exponential ratio
K₅ 1 − tanh²(u/H) Pythagorean identity
K₆ 4σ(2u/H)(1 − σ(2u/H)) Logistic / sigmoid form

Key property: All 6 kernel forms yield identical Λ values — select different forms for Kernel A and B to verify equivalence visually. Poles lie at ±iπH/2 ≈ ±i·2.356 (H=1.5), safely outside the Weil strip |Im(t)| < 0.5.
