How fast planar maps get swallowed by a peeling process

The peeling process is an algorithmic procedure that discovers a random planar map step by step. In generic cases such as the UIPT or the UIPQ, it is known [15] that any peeling process will eventually discover the whole map. In this paper we study the probability that the origin is not swallowed by the peeling process until time n and show it decays at least as n^-2c/3 where c ≈ 0.1283123514178324542367448657387285493314266204833984375… is defined via an integral equation derived using the Lamperti representation of the spectrally negative 3/2-stable Lévy process conditioned to remain positive [12] which appears as a scaling limit for the perimeter process. As an application we sharpen the upper bound of the sub-diffusivity exponent for random walk of [4].
