Titre / Title: Some decisional problems on rational relations
Abstract : In this paper we prove that the problem of deciding whether a deterministic rational relation is star-free is recursively solvable, although the same problem for any rational relation is undecidable. We also prove that a rational relation is star free if and only if it is aperiodic and deterministic.
