椭圆曲线上射影丛的自同态动力学

Dynamics of Endomorphisms for Projective Bundles on Elliptic Curves

Brett Nasserden, Sasha Zotine

AI总结:

本文通过丛的转移函数研究椭圆曲线上射影丛满射自同态的动力学,证明了其Kawaguchi--Silverman猜想,并将结果推广至具有限生成Mori锥的光滑射影簇上的射影分裂丛。

摘要:

我们研究椭圆曲线上射影丛的满射自同态动力学,并将其动力学性质与丛的几何联系起来。作为应用,我们证明了椭圆曲线上射影丛的Kawaguchi--Silverman猜想,从而完成了曲线上所有射影丛的该猜想。我们的方法是使用丛的转移函数。这使我们能进一步证明在具有有限生成Mori锥的光滑射影簇上,射影分裂丛的该猜想。

英文摘要:

We study the dynamics of surjective endomorphisms of projective bundles on elliptic curves and relate their dynamical properties to the geometry of the bundle. As an application we prove the Kawaguchi--Silverman conjecture for projective bundles on elliptic curves, thereby completing the conjecture for all projective bundles on curves. Our approach is to use the transition functions of the bundles. This allows us to further prove the conjecture for projective split bundles on a smooth projective variety with finitely generated Mori cone.
