摘 要：Landis' conjecture states that if $u$ is a non-zero solution to $\Delta u + V u =0 in the Euclidean space, where $V$ is a real, bounded function, then $u$ cannot decay faster than exponentially at infinity. We will discuss the subtleties of the problem and a two-dimensional method, which prohibits the decay $|u(x)| \leq exp(-|x|^{1+\epsilon})$. Based on a joint work with E.Malinnikova, N.Nadirashvili and F. Nazarov.
