本文研究了椭圆曲面上分裂乘性纤维补U的Tate猜想的一个类似。一个主要的结果是给出了上同调的伽罗瓦固定部分的秩的上界。作为应用,我们给出了p进域上的一个椭圆K3曲面,其0环的Chow群的扭转部分是有限的。这将是p进域上的曲面的第一个例子,其几何属是非零的,并且其扭转部分是有限的。
In this paper, we study an analogue of the Tate conjecture forof U, the complement of split multiplicative fibers in an elliptic surface. A main result is to give an upper bound of the rank of the Galois fixed part of the etale cohomology. As an application, we give an elliptic K3 surfaceover a p-adic field for which the torsion part of the Chow groupof 0-cycles is finite. This would be the first example of a surfaceover a p-adic field whose geometric genus is non-zero and for which the torsion part ofis finite.
