论文摘要
在本文中，我们对节点有理非 - $ \ MATHBB {q} $ - fortorial del pezzo 2 fort teger 2进行了分类，对于某些子组$ g \ g \ subset \ operateTornAme {aut}（aut}（x）），这可以是$ g $ - 额外的僵化。
In this paper we classify nodal rational non-$\mathbb{Q}$-factorial del Pezzo threefolds of degree 2 which can be $G$-birationally rigid for some subgroup $G\subset \operatorname{Aut}(X)$.
