Title: Unique continuation for discrete elliptic equations
Abstract: I will prove that a discrete harmonic function which is bounded on a large density of the plane is constant. Based on joint work with William Cooperman and Shirshendu Ganguly.

4-5 pm - Speaker: Aleksandr Logunov (MIT)
Title: Sign of Laplace eigenfunctions
Abstract: The functions sin(kx), cos(kx) are positive on half of the circle. This talk will concern a similar phenomenon of quasi-symmetry for the sign of Laplace eigenfunctions on Riemannian manifolds. We will talk about the distribution of sign and the question of Nazarov, Polterovich and Sodin at which scale quasi-symmetry holds and at which scale quasi-symmetry breaks down. Based on a joint work in progress with Fedya Nazarov.
