Santa Rosalia, the icon of biodiversity,nguages generated by 2-nonterminal grammars, which is in turn a proper subset of the family generated using 3 or more nonterminal symbols. This hierarchy is established by considering grammars over a one-letter alphabet, for which it is shown that 1-nonterminal grammars generate only regular languag

Fighting Europe’s Unemployment in the 1990s symbol and the current pushdown-store top. In this paper, we consider stateless pushdown automata whose size of their pushdown alphabet is limited by a positive integer. More specifically, we establish an infinite hierarchy of language families resulting from stateless pushdown automata with limite

Immigration and the European Labor Markets009, Balan claimed that also the converse holds. Here we show that Balan’s proof of this claim is not correct. Accordingly it is still open whether .-head pushdown automata and centralized PC systems of pushdown automata of degree . working in returning mode accept the same class of languages.
