考虑p-adic域上P^1上的亚纯联络。在许多情况下,例如由Picard-Fuchs方程或Gauss-Manin连接产生的情况,这种连接允许定义在适当的刚性解析子空间上的Frobenius结构。通过研究改变Frobenius升力的影响,我们给出了这种Frobenius结构的有效收敛界。我们还给出了一些例子,表明我们的界限是本质上最优的。
Consider a meromorphic connection on P^1 over a p-adic field. In many cases, such as those arising from Picard-Fuchs equations or Gauss-Manin connections, this connection admits a Frobenius structure defined over a suitable rigid analytic subspace. We give an effective convergence bound for this Frobenius structure by studying the effect of changing the Frobenius lift. We also give some examples indicating that our bound is essentially optimal.
