Landis conjecture is concerned with growth bounds for harmonic functions of Schrödinger operator whose potential in absolute value is bounded by one. We study this problem for real potentials on general graphs and in the Euclidean lattice in particular. (This is joint work with Ujjal Das and Yehuda Pinchover.)
