In this paper we study smooth complex projective varieties X containing a Grassmannian of lines G(1, r) which appears as the zero locus of a section of a rank two nef vector bundle E. Among other things we prove that the bundle E cannot be ample.

Abstract
In this paper we study smooth complex projective varieties X containing a Grassmannian of lines G(1, r) which appears as the zero locus of a section of a rank two nef vector bundle E. Among other things we prove that the bundle E cannot be ample.File in questo prodotto:
