Tsunoda, Shuichiro Degenerations of surfaces. (English) Zbl 0682.14007 Algebraic geometry, Proc. Symp., Sendai/Jap. 1985, Adv. Stud. Pure Math. 10, 755-764 (1987). [For the entire collection see Zbl 0628.00007.] In this article, the third case of the author’s main lemma relating to S- degenerations of surfaces [see M. Miyanishi, ibid. 415-447 (1987; cf. the review above)] is handled, thus completing the proof of the author’s theorem.
