Projective manifolds containing special curves

Lucian Badescu, Mauro C. Beltrametti

Let $Y$ be a smooth curve embedded in a complex projective manifold $X$ of dimension $n \geq 2$ with ample normal bundle $N_{Y ∣ X}$ . For every $p \geq 0$ let $α_{p}$ denote the natural…

On the normal bundle of submanifolds of $P^{n}$

Lucian Badescu

Let $X$ be a submanifold of dimension $d \geq 2$ of the complex projective space $P^{n}$ . We prove results of the following type. i) If $X$ is irregular and $n = 2 d$ then the no…

A Barth-Lefschetz theorem for submanifolds of a product of projective spaces

Lucian Badescu, Flavia Repetto

Let $X$ be a complex submanifold of dimension $d$ of $P^{m} \times P^{n}$ ( $m \geq n \geq 2$ ) and denote by $α\colon\Pic(\mathbb P^m\times\mathbb P^n)\to \Pic(X)$ the restr…
