具有小对偶的射影流形的辛拓扑

The symplectic topology of projective manifolds with small dual

Paul Biran, Yochay Jerby

摘要:

利用辛拓扑学的方法研究了具有小对偶簇的光滑射影簇。我们证明了这些品种的仿射部分是次临界的,超平面类是可逆的量子上同调。我们从中得到几个拓扑和代数几何后果。在我们的工作中的主要工具是赛德尔表示与哈密顿纤维化。

英文摘要:

We study smooth projective varieties with small dual variety using methods from symplectic topology. We prove the affine parts of such varieties are subcritical, and that the hyperplane class is invertible in their quantum cohomology. We derive several topological and algebraic geometric consequences from that. The main tool in our work is the Seidel representation associated to Hamiltonian fibrations.
