两个光滑射影簇之间的AK-等价映射称为单映射,如果该映射的两边都是单光滑blow-ups分解的。本文给出了简单K-等价映射的一个结构定理,从而将对这类映射的研究归结为对特殊Fano流形的研究。作为结构定理的应用,我们给出了简单K-等价映射的例子,并对这类映射进行了几种情况的分类,包括维数不超过8的情况。
AK-equivalent map between two smooth projective varieties is called simple if the map is resolved in both sides by single smooth blow-ups. In this paper, we will provide a structure theorem of simpleK-equivalent maps, which reduces the study of such maps to that of special Fano manifolds. As applications of the structure theorem, we provide examples of simpleK-equivalent maps, and classify such maps in several cases, including the case of dimension at most 8.
