Errata: “Extensions of truncated discrete valuation rings”
Pages: 171 – 174
The purposes of these errata are:
(1) to fill in a gap in the proof of Part (ii) of Proposition 2.2 of [I] (=Proposition 2.1 of [R]), and
(2) to explain the current status of, and wrong points in, the preprint [II] (which will never be published) and the survey paper [R].
We thank Shin Hattori for pointing out the gap (1) and discussions on it, and Takeshi Saito for pointing out a fatal error in [II] and for providing a counterexample to Proposition 3.7 of [II].
