摘要
我们研究了 p-adic 场上曲线的 Weil 表示 ρ,它具有紧凑型的势还原。我们证明了 ρ 可以从它的稳定还原中重建。对于在素数 p 上形式为 yn=f(x) 的超椭圆曲线,其残差特征为指数 n 的素数,我们明确了这一点。
Computing the Weil representation of a superelliptic curve
We study the Weil representation of a curve over a -adic field with potential reduction of compact type. We show that can be reconstructed from its stable reduction. For superelliptic curves of the form at primes whose residue characteristic is prime to the exponent we make this explicit.
