A speciality theorem for curves in
Vincenzo Di Gennaro, Davide Franco
Let be an integral projective curve. One defines the speciality index of as the maximal integer such that , where denote…
Smooth Divisors of Projective Hypersurfaces
Philippe Ellia, Davide Franco, Laurent Gruson
We work over an algebraically closed field of arbitrary characteristic. Ellingsrud-Peskine proved that smooth surfaces in P^4 are subject to strong limitations. Their whole argumen…
On subcanonical surfaces of P^4
Ph. Ellia, D. Franco, L. Gruson
We prove that a smooth, subcanonical surface of P^4 (projective space over an algebraically closed field of characteristic zero) is complete intersection if it is contained in a qu…
On Smooth Divisors of a Projective Hypersurface
Ph. Ellia, D. Franco
We prove an effective bound for the degree of a smooth divisor of a hypersurface of P^n, n>4 (projective space over an algebraically closed field of characteristic zero). Our resul…
