AI 中文摘要
我们证明了所有维数不超过4的仿射终态戈伦斯坦环面簇都是无阻碍的。在四维情形,阻碍空间不一定消失;相反,我们确定了可能的齐次阻碍次数,并构造了同时双参数形变以消除剩余的潜在阻碍。
英文摘要
We prove that every affine terminal Gorenstein toric variety of dimension at most four is unobstructed. In dimension four, the obstruction space need not vanish; instead, we determine the possible homogeneous obstruction degrees and construct simultaneous two-parameter deformations which eliminate the remaining potential obstructions.
