Postulation of General Unions of Lines and Double Points in a Higher Dimensional Projective Space

Edoardo Ballico

pp. 495-504

Abstract

We prove that a general union $X\subset \mathbb {P}^{r}$, $r \geq 6$, of lines and double points has the expected postulation with respect to the hypersurfaces of degree $\geq 4$.
