PDF-!Deterministic Finite and Nondeterministic Automata

Properties of Regular Languages. Each one tape automaton defines a set of tapes a twotape automaton defines a set of pairs of tapes et cetera The structure of the defined sets is studied Various generalizations of the notion of an automaton are introduced and their relation to the Rational .
