Let \((M,g)\) be a compact Riemannian n-manifold without boundary. Consider the corresponding \(L^2\)-normalized Laplace-Beltrami eigenfunctions. In the first part of the lecture, I will give a survey of results which demonstrate how the geometry of \(M\) affects the behaviour of these special functions, particularly their “size” which can be quantified by estimating \(L^p\) norms.
In joint work with Malabika Pramanik (U. British Columbia), I will present in the second part of my lecture a result on the \(L^p\) restriction of these eigenfunctions to random Cantor-type subsets of M. This, in some sense, interpolates between the standard eigenfunction bounds of Sogge ‘88 and the smooth submanifold \(L^p\) restriction results of Burq-Gérard-Tzvetkov ’06.
