چکیده
We give upper bounds for $L^p$ norms of eigenfunctions the Laplacian on compact hyperbolic surfaces in terms a parameter depending growth rate number short geodesic loops passing through point. When genus $g \to +\infty$, we show that random $X$ with respect to Weil-Petersson volume have high probability at most one such loop length less than $c \log g$ small enough > 0$. This allows us deduce $L^2$ normalised are $O(1/\sqrt{\log g})$ large limit any $p 2 + \varepsilon$ $\varepsilon 0$ spectral gap $\lambda_1(X)$ $X$, an implied constant eigenvalue and injectivity radius.

Norms of Geodesic Restrictions for Eigenfunctions on Hyperbolic Surfaces and Representation Theory
We consider restrictions along closed geodesics and geodesic circles for eigenfunctions of the Laplace-Beltrami operator on a compact hyperbolic Riemann surface. We obtain a non-trivial bound on the L-norm of such restrictions as the eigenvalue tends to infinity. We use methods from the theory of automorphic functions and in particular the uniqueness of invariant functionals on irreducible unit...
متن کاملEuclidean Geodesic Loops on High-Genus Surfaces Applied to the Morphometry of Vestibular Systems
This paper proposes a novel algorithm to extract feature landmarks on the vestibular system (VS), for the analysis of Adolescent Idiopathic Scoliosis (AIS) disease. AIS is a 3-D spinal deformity commonly occurred in adolescent girls with unclear etiology. One popular hypothesis was suggested to be the structural changes in the VS that induce the disturbed balance perception, and further cause t...

متن کاملGeodesic Restrictions of Arithmetic Eigenfunctions
Let X be an arithmetic hyperbolic surface arising from a quaternion division algebra over Q. Let be a Hecke–Maass form on X , and let ` be a geodesic segment. We obtain a power saving over the local bound of Burq, Gérard, and Tzvetkov for the L-norm of restricted to `, by extending the technique of arithmetic amplification developed by Iwaniec and Sarnak. We also improve the local bounds for va...
