In 1965 Schützenberger published his famous result that star-free languages () and aperiodic languages () coincide over finite words, often written as. Perrin generalizedto infinite words in the mid 1980s. In 1973 Schützenberger presented another (and less known) characterization of aperiodic languages in terms of rational expressions where the use of the star operation is restricted to prefix codes with bounded synchronization delay and no complementation is used. We denote this class of languages by. In this paper, we present a generalization ofto infinite words. This became possible via a substantial simplification of the proof for the corresponding result for finite words. Moreover, we show thatcan be viewed as more fundamental thanin the sense that the classical 1965 result of Schützenberger and its 1980s extension to infinite words by Perrin are immediate consequences of.
