An intermediate lemma of the split of OpenAI's proof of OAI.SymmetricMahler.symmetric_mahler, carved from OpenAI's openai/math development for this platform. The statement and its proof are OpenAI's (OpenAI, The symmetric Mahler conjecture and its equality cases, OpenAI Math Release, September 22, 2026, result family 87, github.com/openai/math, Apache License 2.0); in Lean it is the declaration OAI.Mahler.MassHypotheses.small_sphere_real_flux_limit of lean/OAI/Analysis/Mahler/Mahler/SphereDensityBridge.lean at commit adc7f12, ported to Lean 4.33.1 and Mathlib 0df444a.

The statement, as published (namespace OAI.Mahler, with open scoped BigOperators TensorProduct, open MeasureTheory Metric):

theorem MassHypotheses.small_sphere_real_flux_limit {k N m : ℕ}
    {U : Set (ComplexEuclidean (k+1))} {f : Fin N → ComplexEuclidean (k+1) → ℂ}
    {G : Fin N → MvPolynomial (Fin (k+1)) ℂ} (h : MassHypotheses (k+1) N m U f G) :
    Filter.Tendsto (fun r => (radiusSphereFlux k (logTau f) r).re)
      (nhdsWithin 0 (Set.Ioi 0)) (nhds (homogeneousSphereFlux k N G))

Definitions. The statement is written with OAI.Mahler.ComplexEuclidean, OAI.Mahler.MassHypotheses, OAI.Mahler.homogeneousSphereFlux, OAI.Mahler.logTau and OAI.Mahler.radiusSphereFlux (definitions bundle OAISMh000 of this split).

Used by. The proofs of OAI.Mahler.MassHypotheses.homogeneousFlux_endpoints_of_transgression and OAI.Mahler.MassHypotheses.sourceCoordinateFlux_limit of this split import it.
