报告摘要：In 1988, F. Blanchard gave a classification of the symbolic dynamics of the class of beta-shifts. Such shifts are strongly related to greedy expansions in non-integer bases. Inspired by this, we present a similar classification for the class of subshifts arisen by unique expansions in non-integer bases. We put special emphasis in describing when the specification property and synchronization holds in this case. If time permits, we will also present some advances in the general classification of lexicographic subshifts and pose some questions.
