On the languages generated by context-sensitive fuzzy grammars

It is proved that the family of the languages generated by 1-fold fuzzy grammars with context-sensitive rules and grade larger than λ,0≦λ<1, is equal to the family of the context sensitive languages. Also, one shows that the family of the languages generated by fuzzy grammars with context-sensitive rules and grade larger than λ,0≦λ<1, is included in the family of the context-sensitive languages.
