| Abstract | Abstract. Let X be a Fano manifold of pseudoindex iX whose Picard number is at least two and let R be an extremal ray of X with exceptional locus Exc(R). We prove an inequality which bounds the length of R in terms of iX and of the dimension of Exc(R) and we investigate the border cases. In particular we classify Fano manifolds X of pseudoindex iX obtained blowing up a smooth variety Y along a smooth subvariety T such that dim T < iX. 1. |
