Abstract
Deterministic 1-way stack automata (SA) are generalized to include jumps, and it is established that for any SA there exists an equivalent semi-real-time Jump SA. Applying a well-known information theoretic argument to the Jump SA, we prove that certain languages cannot be SA languages. Parallel to Cole's treatment ( J. Assoc. Comput. Mach. (1971), 306–328) of pushdown automata, we show that SA's can be reduced to real-time n -dimensional cellular automata.
