We present a relation between the sets accepted by two-way pushdown automata and certain tape complexity classes of off-line Turing machines. Specifically, let L be a language accepted by a nondeterministic off-line Turing machine T. Let T have a t-symbol storage-tape alphabet. If for all but a fini

We describe a class of simple transitive semiautomata that exhibit full exponential blow-up during deterministic simulation. For arbitrary semiautomata we show that it is PSPACE-complete to decide whether the size of the accessible part of their power automata exceeds a given bound. We comment on th
