This thesis consists of three chapters including ten sections, which focus on beta-expansions, related digit frequencies, generalized Thue-Morse sequences and their relations. Chapter 1 is devoted to greedy beta-expansions and related digit frequencies. In Section 1.1, we study the distributions and numbers of full and non-full words in greedy beta-expansions. In Sections 1.2 and 1.3, by studying Bernoulli-type measures and variational formulae respectively, we obtain some exact formulae for the Hausdorff dimension of some digit frequency sets in greedy beta-expansions.Chapter 2 is devoted to general beta-expansions (not only the greedy ones) and related digit frequencies. In Section 2.1, we systematically study expansions in multiple bases...
