Elliptic Curves Over A p-adic Field With Fake Ordinary Good Reduction

Key Points

This research aims to understand the kernel of the Albanese map for elliptic curves in p-adic fields.
Analyzed the kernel structure for a product of elliptic curves.
Applied theoretical frameworks relevant to p-adic fields.
Examined the effect of field ramification on kernel properties.
Proved that the kernel becomes p-divisible under small ramification conditions.
Identified relationships between ramification and kernel attributes.

Abstract

We investigate the structure of the kernel of the Albanese map for a product of curves over a p-adic field. Specifically, we prove that the kernel becomes p-divisible when the ramification of the base field is sufficiently small.
