Global localization conjecture for weight-one Kato homology
Global localization conjecture for weight-one Kato homology
Let be a global field, let be the completion at a place , and set . Let and .
Global localization conjecture. For , there is an isomorphism
and for there is a short exact sequence
where runs over all places of . This is a local-global description of the weight-one Kato homology groups.
