Finite Automata HF

Finite Automata in Hereditarily Finite Set Theory. Finite Automata, both deterministic and non-deterministic, for regular languages. The Myhill-Nerode Theorem. Closure under intersection, concatenation, etc. Regular expressions define regular languages. Closure under reversal; the powerset construction mapping NFAs to DFAs. Left and right languages; minimal DFAs. Brzozowski’s minimization algorithm. Uniqueness up to isomorphism of minimal DFAs.
