利用由秩为4的向量丛的全空间构成的特殊完整流形的球对称性的一个证明,给出了Bryant和Salamon构造的特殊完整流形上的G2和Spin(7)瞬子的构造.在G2情形下,我们证明了在渐近锥模型中,在近Kähler S3 × S3上的Hermitian Yang-Mills联络是渐近的.
We give a construction of G 2 and S p i n (7) instantons on exceptional holonomy manifolds constructed by Bryant and Salamon, by using an ansatz of spherical symmetry coming from the manifolds being the total spaces of rank-4 vector bundles. In the G 2 case, we show that, in the asymptotically conical model, the connections are asymptotic to Hermitian Yang–Mills connections on the nearly Kähler S 3× S 3.
