Semigruppi, monodia e gruppi liberi
Parole chiave:
Semigruppi liberi, monoidi liberi, gruppi liberi, problema della parola, problema del coniugioAbstract
Lo scopo di questo articolo è quello di presentare l’esperienza svolta con docenti di matematica e studenti di 21 anni di età inerente alcune strutture algebriche astratte e osservare come questi concetti siano stati percepiti.
