Wright's Friedman conjecture for random hyperbolic surfaces
Wright's Friedman conjecture for random hyperbolic surfaces
Let be a random compact hyperbolic surface of genus , sampled according to the Weil–Petersson probability measure. Write for the number of eigenvalues of the Laplacian in the interval , counted with multiplicity. Wright's conjecture. For any sufficiently small ,
Equivalently, for every fixed sufficiently small , with high probability the only eigenvalue below is the trivial eigenvalue . This is the random-hyperbolic-surface analogue of Friedman's theorem for random regular graphs; the conjecture concerns the spectral gap under Weil–Petersson measure and remains open in the source.
