关于具有不可分裂控制族有理曲线的Fano流形

On Fano manifolds with an unsplit dominating family of rational curves

Carla Novelli

摘要:

研究了含有不可分裂控制族有理曲线的Fano流形$X$,证明了当$X$具有伪指标$i_X = (\dim X)/3$或维数$\dim X=6$时,广义Mukai猜想成立.我们还证明了这个猜想对所有具有$i_X > (\dim X)/3$的Fano流形都成立。

英文摘要:

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 $i_X > (\dim X)/3$.
