摘要

．利用a . J. Sommese的一个合论结果和SGA7的一个命题，我们得到了一个光滑三折的完整列表，其中作用在其光滑超平面截面h2上的单群为Z / 2z。这种分类的可能性是由f·l·扎克在1991年宣布的。

On threefolds with the smallest nontrivial monodromy group

. Using an adjunction-theoretic result due to A. J. Sommese together with a proposition from SGA7, we obtain a complete list of smooth threefolds for which the monodromy group acting on H 2 of its smooth hyperplane section is Z / 2 Z . The possibility of such a classiﬁcation was announced by F. L. Zak in 1991.
