论文摘要
本注释的主要目的是在单位球体中的某些等型超曲面上构建几乎复杂或复杂的结构。结果，建造了$ s^1 \ times s^7 \ times s^6 $的复杂结构，以及$ s^1 \ times s^3 \ times s^2 $，构建了消失的第一chern类。
The main purpose of this note is to construct almost complex or complex structures on certain isoparametric hypersurfaces in unit spheres. As a consequence, complex structures on $S^1\times S^7\times S^6$, and on $S^1\times S^3\times S^2$ with vanishing first Chern class, are built.
