Residue invariance of weight-one Kato homology under regular proper models
Residue invariance of weight-one Kato homology under regular proper models
Let be a local field of characteristic with finite residue field , let be a smooth variety over , and let be a model of over the valuation ring . Write for its special fiber. For and , let denote the residue map from weight-one Kato homology of to weight-zero Kato homology of .
Residue invariance conjecture. If the model is proper over and regular, then
is an isomorphism for all and .
