Abstract
In this paper, we investigate uniform spectral gaps for Weil-Petersson random hyperbolic surfaces with not many cusps. We show that if where , then for any , a random cusped hyperbolic surface in has no eigenvalues in . If is close to , this gives a new uniform lower bound for the spectral gaps of Weil-Petersson random hyperbolic surfaces. The major contribution of this work is to reveal a critical phenomenon of ``second order cancellation".
