AI总结:

本文研究函数域算术中Anderson A-动机的调节器概念,证明了A-动机上同调的有限性,并在特定重量条件下显示调节器源和目标的维度相同,但发现调节器像可能不具有满秩,影响了Beilinson猜想的类比。

英文摘要:

As a natural sequel to the study of A-motivic cohomology initiated in "On the integral part of A-motivic cohomology", we develop a notion of regulator for rigid analytically trivial Anderson A-motives. In accordance with the conjectural picture over number fields, we define it as the morphism at the level of extension modules induced by the exactness of the Hodge-Pink realization functor. The purpose of this article is twofold: first, we prove a finiteness result for A-motivic cohomology; second, under a weight assumption, we show that the source and the target of the regulator have the same dimension. It came as a surprise to the author that the image of this regulator may fail to have full rank, thereby preventing an analogue of Beilinson's celebrated conjecture from holding in our setting.
