The Dionysiac Chronotope (Pre-1799–1799)eterministic finite automata. In particular, we consider Boolean operations, concatenation, iteration, and λ-free iteration. Most of the bounds are tight in the exact number of states, i.e. the number is sufficient and necessary in the worst case. For the complementation of infinite languages a tigh

A Remark about Quadratic Trace Equationsnown linear time algorithm for quadratic word equations with length constraints to cope with involutions. Finally, we show that the same linear-time result cannot be expected for trace equations. We obtain an NP-hardness result.
