Here we prove a numerical bound implying that, except for smooth plane conics in characteristic 2, no complete linear system maps birationally a smooth curve into a projective space with a strange curve as image.
Si dimostra qui una diseguaglianza numerica che ha come applicazione il fatto che le coniche piane in caratteristica 2 corrispondono agli unici sistemi lineari completi su una curva liscia \( X \) che determinano un morfismo birazionale \( h \) da \( X \) in uno spazio proiettivo con \( h(X) \) curva «strana».
