Dynamical systems of translation groups on a torus

Abstract

The criterion for linearizability is obtained by a property of denominator of rational numbers that are given by continued fractions. We can regard this criterion as a condition given by behaviors of orbits of dynamical systems of translation groups on a one-dimensional real torus. By using continued fractions, we obtain a criterion that is an analogous phenomenon in several complex variables that is determined by behaviors of dynamical systems of translation groups on a one-dimensional complex torus.
