Durată: Lansat în 1993

Cuvinte cheie: Limbaje formale, cuvinte primitive

Obiective:

Cercetarea proprietăţilor combinatorice şi a problemelor de decizie ale unor limbaje speciale. În mod deosebit, studiul proprietăţilor combinatorice (lema de pompare, lema de interschimbare) a mulţimii Q a cuvintelor primitive, şi alte probleme adiacente. Q este non-liniară şi independentă de context, nu este non-ambiguă, dar îndeplineste toate lemele de pompare şi lema de interschimbare. Problema dacă limbajele generate de gramatici independente de context conţin numai cuvinte primitive, sau toate cuvintele primitive, este o problemă nedecidabilă.
