We extend the theorem of Fine and Wilf to words having three periods. We then define the set 3-PER of words of maximal length for which such result does not apply. We prove that the set 3-PER and the sequences of complexity 2n + 1, introduced by Amoux and Rauzy to generalize Sturmian words, have the

β¦ Synopsis
A partial word is a word that is a partial mapping into an alphabet. We prove a variant of Fine and Wilf's theorem for partial words, and give extensions of some general combinatorial properties of words.

In this paper, we establish a new limit theorem for partial sums of random variables. As corollaries, we generalize the extended Borel-Cantelli lemma, and obtain some strong laws of large numbers for Markov chains as well as a generalized strong ergodic theorem for irreducible and positive recurrent
In 1974 Cruse gave necessary and suf cient conditions for an rΓs partial latin square P on symbols r 1 , r 2 ,...,r t , which may have some unfilled cells, to be completable to an nΓn latin square on symbols r 1 , r 2 ,...,r n , subject to the condition that the unfilled cells of P must be lled with
