BGW.StableTrees.HeightContinuityHolder

Hölder regularity on all bounded horizons #

For each exponent below the stable height exponent, choose a sufficiently high moment. Horizon modifications agree with the common continuous reconstruction by indistinguishability. A countable intersection then covers every real horizon.

Almost surely the continuous height is locally γ-Hölder for every γ < 1 - 1/θ.
