The generalized Mukai conjecture

Proves the generalized Mukai conjecture: every positive-dimensional smooth complex projective Fano manifold of dimension n, Picard number ρ and pseudoindex ι satisfies ρ(ι−1)≤n\rho(\iota-1)\le n, with equality exactly for (Pι−1)ρ(\mathbb P^{\iota-1})^\rho. Here the pseudoindex is the least anticanonical degree of a rational curve.
