A Class of Countably Covered Two-Dimensional Sofic Shifts
<|reference_start|>A Class of Countably Covered Two-Dimensional Sofic Shifts: A multidimensional sofic shift is called countably covered if it has an SFT cover containing only countably many configurations. In contrast to the one-dimensional setting, not all countable sofic shifts are countably covered. We study a subclass of countable shift spaces and characterize the countably covered sofic shifts among them.<|reference_end|>
