摘要对Hetale =0的半稳定椭圆曲面的去奇异纤维积进行了分类。这类簇可以在超奇异三重性、平凡正则丛簇的变形理论和刚性卡-丘三重性的算术退化的研究中发挥作用。
Abstract Desingularized fiber products of semi-stable elliptic surfaces with Hetale3=0 are classified. Such varieties may play a role in the study of supersingular threefolds, of the deformation theory of varieties with trivial canonical bundle, and of arithmetic degenerations of rigid Calabi–Yau threefolds.
