Laufzeit: seit 1993

Schlagworte: Formale Sprachen; Primitive Wörter; Iterationslemmata

Ziele:

Die Untersuchung von kombinatorischen Eigenschaften und Entscheidungsproblemen spezieller Sprachen wurde fortgesetzt. Die kombinatorischen Eigenschaften und Entscheidungsprobleme der Menge Q aller primitiven Wörter wurden weiter untersucht. Speziell wurden alle kontextfreien Grammatiken bis zu einer Anzahl von 4 Nonterminals, welche nur primitive Wörter erzeugen, charakterisiert. Für weitere Sprachklassen, wie algebraische Sprachen mit Shuffle, verteilter Katenation und anderen Operationen, wurde gezeigt, dass sie Q nicht enthalten. Ferner wurden weitere Iterationslemmata für kontextfreie und lineare indizierte Sprachen gefunden. Dazu gab es ein bilaterales deutsch-ungarisches Projekt "Formale Sprachen" in den Jahren 1995-1997. Für 2001-2002 wurde ein weiteres deutsch-ungarisches Projekt "Formale Sprachen" bewilligt. Dieses wurde bis Ende 2004 verlängert.
