摘要：Consider the dynamical systems of multiplication by two modulo one and the multiplication by three modulo one. We study the sets of points whose orbits by these two dynamical systems are simultaneously approaching to a given point. With given speeds of approximation, some sharp estimations of the Hausdorff dimension of such a set are obtained. This is a joint work with Bing LI.
