An Introduction to Formal Languages and Automata 6th. While formal language theory usually concerns itself with formal languages that are described by some syntactical rules, the actual definition of the concept "formal language" is only as above: a (possibly infinite) set of finite-length strings composed from a given alphabet, no more and no less., view deply inп¬‚uenced the textbook presentation of automata theory. Results about the expressive power of machines, equivalences between models, and closure properties, received much attention, while constructions on automata, like the powerset or product construction, often played a subor-dinate role as proof tools.
