Near-optimal spectral-gap meta-conjecture for random hyperbolic surfaces
Near-optimal spectral-gap meta-conjecture for random hyperbolic surfaces
Let be a sequence of random finite-area hyperbolic surfaces such that
Write for the first positive Laplace eigenvalue. Random hyperbolic-surface spectral-gap meta-conjecture. For every ,
The claim predicts that random hyperbolic surfaces asymptotically achieve the universal-cover threshold with high probability. It is presented as a meta-conjecture motivated by the analogy with random regular graphs and Selberg's conjecture; the source does not give a resolution.
