Sunto

Si costruiscono nuove curve piane di ordine dieci dotate di sei punti [3, 3] che non giacciono su una conica e curve di ordine dieci dotate di cinque punti [3, 3] e di un punto quadruplo ancora non giacenti su una conica. Nella seconda famiglia si è presentata una curva irriducibile.

Abstract

We construct new degree ten plane curves having six [3, 3] points that do not belong to a conic and degree ten plane curves with five [3, 3] points and a quadruple point, having the six singularities that again do not lie on a conic. In the second family we find an irriducible curve.
