Abstract：

  In this talk, we address non-emptiness problems, spatial entropy and dynamical zeta functions of multi-dimensional shift spaces. Shifts of finite type (SFTs) is a basic of shift spaces. For 1-d SFTs, the results of these topics are well-known and complete. However, for multi-dimensional SFTs, corresponding results are fewer. Furthermore, sofic shifts, a natural generalization of SFTs, are also studied.
