Contribution
It defines the logarithmic Hasse symbol, studies its fundamental properties, and establishes a logarithmic version of the principal ideal theorem, extending classical ramification results.
Findings
Expression of the defect of the -adic Hasse principle
Logarithmic version of the principal ideal theorem
Properties of the logarithmic Hasse symbol
Abstract
In this article, we define the logarithmic Hasse symbol in the same way as the usual one but in the context of the logarithmic ramification. We study its fondamental properties. The interesting point is that we get an expression of the defect of the \^a-adic Hasse principle. Then we study particular cases and get a logarithmic version of the principal ideal theorem.
