Tiivistelmä
It is proved that the language family generated by Boolean grammars is effectively closed under injective gsm mappings and inverse gsm mappings (where gsm stands for a generalized sequential machine).The same results hold for conjunctive grammars, unambiguous Boolean grammars and unambiguous conjunctive grammars
