我们证明了局部域K上的Frobenius-半单Weil表示是由它在K的扩张上的欧拉因子决定的。这种构造是明确的,并且我们对附加在椭圆曲线和亏格2曲线上的L-ADDIC表示进行了说明。作为应用,根据Birch-Swinnerton-Dyer猜想,我们在Q上构造了一个绝对简单的二维阿贝尔簇,它的所有二次扭曲必有正阶。
We show that a Frobenius-semisimple Weil representation over a local fieldK is determined by its Euler factors over the extensions ofK. The construction is explicit, and we illustrate it for l-adic representations attached to elliptic and genus 2 curves. As an application, we construct an absolutely simple 2-dimensional abelian variety over Q all of whose quadratic twists must have positive rank, according to the Birch-Swinnerton-Dyer conjecture.
