dc.description.abstract We give upper bounds for Lp norms of eigenfunctions of the Laplacian on compact hyperbolic surfaces in terms of a parameter depending on the growth rate of the number of short geodesic loops passing through a point. When the genus g → +∞, we show that random hyperbolic surfaces X with respect to the WeilPetersson volume have with high probability at most one such loop of length less than c log g for small enough c > 0. This allows us to deduce that the Lp norms of L2 normalised eigenfunctions on X are O(1/√log g) with high probability in the large genus limit for any p > 2 +ε for ε > 0 depending on the spectral gap λ1(X) of X, with an implied constant depending on the eigenvalue and the injectivity radius. en
