Norms of Eigenfunctions on Regular Graphs and on the Sphere
Shimon Brooks, Etienne Le Masson
We prove upper bounds on the norms of eigenfunctions of the discrete Laplacian on regular graphs. We then apply these ideas to study the norms of joint eigenfunctions o…

Logarithmic-scale Quasimodes that do not Equidistribute
Shimon Brooks
Given any compact hyperbolic surface , and a closed geodesic on , we construct of a sequence of quasimodes on whose microlocal lifts concentrate positive mass on the geod…
