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