We prove that if X is a finite area non-compact hyperbolic surface, then for any ϵ > 0, with probability tending to one as n → ∞, a uniformly random degree n Riemannian cover of X has no eigenvalues of the Laplacian in [0, 1 4 − ϵ) other than those o...

We show that for any ε>0⁠, α∈[0, 1 2 )⁠, as g→∞ a generic finite-area genus g hyperbolic surface with n=O(gα) cusps, sampled with probability arising from the Weil–Petersson metric on moduli space, has no non-zero eigenvalue of the Laplacian below 1...
