设X是k的有限非分歧扩张上的光滑射影曲线的乘积。假设X的Albanese簇具有良好的约化并且X具有ak-有理点。我们提出以下猜想。Albanese mapisp-divisible的内核。当p是奇素数时,我们对椭圆曲线与某些交换簇的主齐性空间的乘积族证明了这个猜想。利用这一点,我们为Colliot-Thélène和Santiago(杜克数学杂志48(2):421-447,1981)以及Kato和Saito(当代数学,第55卷:255-331,1986)的零圈的局部到整体猜想提供了一些证据。
LetXbe a product of smooth projective curves over a finite unramified extensionkof. Suppose that the Albanese variety ofXhas good reduction and thatXhas ak-rational point. We propose the following conjecture. The kernel of the Albanese mapisp-divisible. Whenpis an odd prime, we prove this conjecture for a large family of products of elliptic curves and certain principal homogeneous spaces of abelian varieties. Using this, we provide some evidence for a local-to-global conjecture for zero-cycles of Colliot-Thélène and Sansuc (Duke Math J 48(2):421–447, 1981), and Kato and Saito (Contemporary Mathematics, vol. 55:255–331, 1986).
