In the moduli space of curves of genus $g$, $\mathcal{M}_g$, let $\mathcal{GP}_g$ be the locus of curves that do not satisfy the Gieseker-Petri theorem. In the genus seven case we show that $\mathcal{GP}_7$ is a divisor in $\mathcal{M}_7$.
Nello spazio dei moduli delle curve di genere $g$, $\mathcal{M}_g$, indichiamo con $\mathcal{GP}_g$ il luogo delle curve che non soddisfano il teorema di Gieseker-Petri. In questo lavoro noi proviamo che nel caso di genere sette, $\mathcal{GP}_7$ è un divisore di $\mathcal{M}_7$.
