Abstract

Let E be the restriction of the null-correlation bundle on P3\mathbb{P}^{3} to a hyperplane. In this article, we show that the projective bundle P(E)\mathbb{P}(E) is isomorphic to a blow-up of a non-singular quadric in P4\mathbb{P}^{4} along a line. We also prove that for each d2d \geq 2, there are hypersurfaces of degree d containing a line in P4\mathbb{P}^{4} whose blow-up along the line is isomorphic to the projective bundle over P2\mathbb{P}^{2}.
