六球上的瞬子和扭子

Instantons on the six-sphere and twistors

Olaf Lechtenfeld, Alexander D. Popov

摘要:

我们考虑六球S^6=G_2/SU(3)及其扭量空间Z=G_2/U(2)与S^6上的SU(3)-结构相联系。证明了S^6上光滑向量丛上的埃尔米特杨-米尔斯联络(瞬子)等价于扭量空间Z上向量丛上的平坦部分联络。简要讨论了与田氏切瞬子的关系及其扭量描述。

英文摘要:

We consider the six-sphere S^6=G_2/SU(3) and its twistor space Z=G_2/U(2) associated with the SU(3)-structure on S^6. It is shown that a Hermitian Yang-Mills connection (instanton) on a smooth vector bundle over S^6 is equivalent to a flat partial connection on a vector bundle over the twistor space Z. The relation with Tian's tangent instantons on R^7 and their twistor description are briefly discussed.
