Title: Mobius disjointness for topological models of ergodic systems with discrete spectrum Abstract: We provide a criterion for a point satisfying the required disjointness condition in Sarnak¡¯s Mobius Disjointness Conjecture. As a direct application, we have that the conjecture holds for any topological model of an ergodic system with discrete spectrum. This is a joint work with Zhiren Wang and Guohua Zhang.
