Description

The Banff International Research Station will host the "Bounds for restrictions of Laplace eigenfunctions" workshop in Banff from October 15, 2017 to October 22, 2017.


In this workshop we plan to study the behavior of the $L^2$-mass of restricted Laplace eigenfunctions. We will be working on compact surfaces without boundary, and we will restrict the eigenfunctions to curves that are not a segment of a geodesic. We conjecture that the $L^2$-mass of the restrictions of quantum ergodic eigenfunctions to the curve $H$ are uniformly bounded above and below by a constant as the eigenvalue grows to infinity. Furthermore, the $L^2$-mass of any eigenfunctions to the curve $H$ have an exponential lower bound. Understanding these questions will have profound implications for the study of the nodal sets of eigenfunctions.
