Final sentential forms
Original language description
Let G be a context-free grammar with a total alphabet V, and let F be a final language over an alphabet W as a subset of V. A final sentential form is any sentential form of G that, after omitting symbols from V-W, it belongs to F. The string resulting from the elimination of all nonterminals from W in a final sentential form is in the language of G finalized by F if and only if it contains only terminals. The language of any context-free grammar finalized by a regular language is context-free. On the other hand, it is demonstrated that L is a recursively enumerable language if and only if there exists a propagating context-free grammar G such that L equals the language of G finalized by {w#rev(w):string w over alphabet {0,1}}, where rev(w) is the reversal of w.
