In April 2003, Chern began a study of almost-complex structures on the six-sphere, with the idea of exploiting the special properties of its well-known almost-complex structure invariant under the exceptional group G 2 . While he did not solve the (currently still open) problem of determining whether there exists an integrable almost-complex structure on S 6 , he did prove a significant identity that resolves the question for an interesting class of almost-complex structures on S 6 .

S.-S。陈对六球体上几乎复杂结构的研究
2003 年 4 月,陈先生开始研究六球上的准复结构,其想法是利用其著名的异群下准复结构不变量的特殊性质G 2 . 虽然他没有解决(目前仍然悬而未决的)确定是否存在可积的几乎复杂结构的问题小号 6 ,他确实证明了一个重要的身份,它解决了一类有趣的几乎复杂结构的问题小号 6 .
