Alternating Tree Automata and Parity Games
Since Büchi’s work in 1960 , automata play an important role in logic. Numerous different notions of automata provide decision and complexity results in various kinds of logic. Often, one develops a method to translate some given formula ϕ into an appropriate finite automaton A such that L(ϕ) = L(A). Such a translation reduces the model checking problem and the satisfiability problem in some logic to the word problem and the emptiness problem for finite automata. Moreover, such a translation provides algorithms to solve the model checking and the satisfiability problems on a computer. Consequently, one is interested in the decidability and the complexity of the word and emptiness problems of automata.
