The goal of this thesis was to study definability questionsabout finite-state transducers and in particular two-waytransducers. It is known that two-way transducers cover a larger classof transductions than one-way transducers. Then the first question wetackled is the one-way definability problem: is it possible torealize a given two-way transduction by a one-way transducer? Thisproblem was shown to be decidable for functionaltransducers (we also show as a side result that one-way definability becomes undecidable for non-functional transducers) but the decision procedure had non-elementary complexity.We proposed a characterization of one-way definability thatallows us to decide it in double-exponential space, and provide anequivalent one-w...
