Abstract

This paper introduces and studies a whole variety of derivation modes in scattered context grammars. These grammars are conceptualized just like classical scattered context grammars except that during the applications of their rules, after erasing n nonterminals, they can insert new substrings possibly at different positions than the original occurrence of the erased nonterminal.The paper concentrates its attention on investigating the generative power of scattered context grammars  working under these derivation modes. It demonstrates that all of them are computationally complete--that is, they characterize the family of recursively enumerable languages.
