Problems related to the concentration of eigenfunctions

Abstract

We survey recent results related to the concentration of eigenfunctions. We also prove some new results concerning ball-concentration, as well as showing that eigenfunctions saturating lower bounds for L1L^1-norms must also, in a measure theoretical sense, have extreme concentration near a geodesic.
