整体函数域上Tate猜想的秩不等式

A rank inequality for the Tate Conjecture over global function fields

Christopher Lyons

摘要:

继D. Ramakrishnan,我们解释如何L。Lafforgue的模性定理和H. Jacquet和J.Shalika证明了与Tate猜想相关的如下结果:对于定义在整体函数域上的光滑、射影、几何连通簇,代数秩小于或等于解析秩.还讨论了数域的类似(开放)问题和一个简单的扩展Lafforgue定理,以消除“有限阶字符”的假设。所有结果都可能是“专家已知的”,但似乎没有写下来。

英文摘要:

Following D. Ramakrishnan, we explain how L. Lafforgue's modularity theorem and an analytic theorem of H. Jacquet and J. Shalika can be applied to prove the following result related to the Tate Conjecture: for a smooth, projective, geometrically-connected variety defined over a global function field, the algebraic rank is less than or equal to the analytic rank. Also discussed is the analogous (open) question for number fields and an easy extension of Lafforgue's theorem to remove the "finite-order character" assumption. All results are likely "known to the experts", but don't appear to be written down.
