摘要: 证明具有光滑非平凡对合〖WTBX〗T的r维闭流形M, 如果对合的不动点集为F=∪mi=1HPi(2n), 其中 n≥1, 则有: (1) 当r=16n时, (M,T)协边于(F×F,twist); (2) 当r>8n, 且r≠16n时, (M,T)协边于零

关键词: 对合, 协边, 不动点集

Abstract: For any nontrivial differentiable involution on an r-dimensional manifold (M,T) whose fixed point set F is a disjoint union of quaternionic projective spaces of constant dimension 8n(n≥1), it is concluded that if r=16n then (M,T) is bordant to (F×F,twist), if 8n

Key words: involution, bordism, fixed point set
