In this paper, we prove that if the circle acts on an 8-dimensional compact almost complex manifold M with 4 fixed points, all the Chern numbers and the Hirzebruch \(\chi _y\)-genus of M agree with those of \(S^2 \times S^6\). In particular, M is unitary cobordant to \(S^2 \times S^6\).

在具有4个固定点的8维几乎复杂的流形上进行圆周动作

在本文中,我们证明,如果圆作用在8维紧凑几乎复杂歧管中号与4个固定点,所有的陈数和希策布鲁赫\(\智_y \)的-genus中号与那些同意\( S ^ 2 \ times S ^ 6 \)。特别地,M\(S ^ 2 \ times S ^ 6 \)的一元余弦。
