Nearly optimal spectral gaps for random Belyi surfaces (2511.02517v1)
Published 4 Nov 2025 in math.SP, math.DG, math.GT, and math.RT
Abstract: In this paper, we show that for any $\epsilon>0$, a random hyperbolic surface in the Brooks-Makover model has a spectral gap greater than $\frac{1}{4}-\epsilon$, confirming the nearly optimal spectral gap conjecture in this model.
