本文研究了Albanese核T_F(E x E), p进域F上的椭圆曲线E。主要结果给出了对任意奇素数p,从T_F(E x E)/p到Galois上同调群H^2(F,E[P]<$E[P])的Galois符号映射的核和象的信息,对E/F平凡,不要求p-扭点是F-有理数,甚至不要求Galois模E[P]是半单的.关键的一步是证明当有限Galois模E[P]被pro-p-惯性群I_p非平凡地作用时,象为零。 E[P]是合适的非分歧的。即将出版的续集将讨论全球问题。
This article studies the Albanese kernel T_F(E x E), for an elliptic curve E over a p-adic field F. The main result furnishes information, for any odd prime p, about the kernel and image of the Galois symbol map from T_F(E x E)/p to the Galois cohomology group H^2 (F,E[P] ⊗ E[P]), for E/F ordinary, without requiring that the p-torsion points are F-rational, or even that the Galois module E[P] is semisimple. A key step is to show that the image is zero when the finite Galois module E[P] is acted on non-trivially by the pro-p-inertia group I_p. Non-trivial classes in the image are also constructed when E[P] is suitably unramified. A forthcoming sequel will deal with global questions.
