Deterministic reconstruction in mass:construction. A countable family locally dense in compactly supported continuous functions, including nonnegative exhaustion cutoffs, determines one Radon limit.

  1. structure OAI.SLEExactGauge.LocalTestFamily line 21

    Source documentation

    A countable determining family with explicit support control. Density is in the uniform norm within each compact exhaustion set.

    Source documentation

    Compactly supported integrals are Cauchy once the countable tests converge. Cutoff convergence supplies the uniform local mass bounds.
