摘要: 设(M,T)是一个带有光滑对合T的光滑闭流形, T在M上的不动点集为F. 考虑F=RP5×RP2s带有对合的闭流形(M,T)的等变协边分类, 给出了完全决定非协边于零的带有对合的闭流形(M,T)的维数及等变协边类.

关键词: 对合, 不动点集, 射影空间, 示性类, 协边类

Abstract: Let (M,T) be a smooth closed manifold with a smooth involution T and F={x|T(x)=x, x∈M}the fixed point set of Ton M, the authors studied the closed mainfold (M,T) with involution Tof F=RP5×RP2s, and determined the possible dimensions and equivariant cobordism classification of (M,T).

Key words: involution, fixed point set, projective space, charac teristic class, cobordism class
