On the generating sequences of regular languages on k-symbols
Abstract : The main result is a characterization of the generating sequences of the length of words in a regular language on k symbols. We say that a sequence s of integers is regular if there is a finite graph G with two vertices i, t such that sn is the number of paths of length n from i to t in G. Thus the generating sequence of a regular language is regular. We prove that a sequence s is the generating sequence of a regular language on k symbols if and only if both sequences s = ( sn)n≥0 and t = (kn − sn)n≥0 are regular.
