Sul numero delle parole senza quadrati parzialmente abeliani per un alfabeto di tre lettere

Abstract. We present results from some of our previous works, most of them done in collaboration with R. Cori, concerning the notion of partially abelian square-free words; in particular we examine results obtained on the multinomial expansion of such words when the alphabet has three letters.

The paper has been finally published as a joint paper with Robert Cori under the title "On the number of partially abelian square-free words on a three-letter alphabet" in Theoret. Comput. Sci. 81 (1991), 147-153.
