On Operations over Language Families
Original language description
Let O and F be an operation and a language family, respectively. So far, in terms of closure properties, the classical language theory has only investigated whether O(F) is strictly included in F, where O(F) is the family resulting from O applied to all members of F. If O(F) is strictly included F, F is closed under O; otherwise, it is not. This paper proposes a finer and wider approach to this investigation. Indeed, it studies almost all possible set-based relations between F and O(F), including O(F) = empty set; F is not a subset of O(F), O(F) is not a subset of F, F intersection O(F) is not empty set; F intersection O(F) = empty set, O(F) is not empty set; O(F) = F; and F is a subset of O(F). Many operations are studied in this way. A sketch of application perspectives and open problems closes the paper.
