| 抄録: | In 1980s, Deligne proved that, if two complete discrete valuation fields with perfect residue fields are close enough, then their absolute Galois groups are isomorphic to each other modulo certain upper ramification subgroups. In this article, we give a brief survey on the author s generalization of this result to the case where the residue fields are imperfect. |
