%0 Journal Article %T On Fano manifolds with an unsplit dominating family of rational curves %A Carla Novelli %J Mathematics %D 2011 %I arXiv %X We study Fano manifolds $X$ admitting an unsplit dominating family of rational curves and we prove that the Generalized Mukai Conjecture holds if $X$ has pseudoindex $i_X = (\dim X)/3$ or dimension $\dim X=6$. We also show that this conjecture is true for all Fano manifolds with $i_X > (\dim X)/3$. %U http://arxiv.org/abs/1109.1979v1
