Abstract:

A pre-AFL is a family of sets of words closed under certain basic operations. Each pre-AFL contains all regular sets and becomes an abstract family of languages when closed under length-increasing homomorphism. A number of situations in automata and language theory giving rise to pre-AFL are presented. Author
