Automata with a time-variant structure and supply-demand theorems (Q700261)

This paper follows some older papers studying finite automata with time-variant structure, i.e., with the transition function being depended on the time where the time is represented by the set of nonnegative integers. Here the author considers a more general model when also the set of states is time-dependent. He then provides some results showing how the growth of the state set constraints the accepted languages.
