Una curva ottimale su Fq è definita come una curva proiettiva, liscia e assolutamente irriducibile definita sul campo finito Fq che ha il massimo numero di punti Fq-razionali consentito per il suo genere. I primi esempi di crve ottimali definite su F2 risalgono agli anni ottanta e sono dovuti a J.-P.Serre: applicando tecniche di teoria del corpo delle classi, Serre costruisce queste curve come ricoprimenti abeliani della retta proiettiva o di una curva ellittica di equazione data definita su F2. Dimostriamo in questa tesi che una curva ottimale di genere g definita su F2 è unica a meno di F2-morfismi per genere g=1,...,5. In questo senso gli esempi dati da Serre sono gli unici esempi di curve ottimali possibili. D'altra parte, a meno di F2-...
