摘要

f,g:XG/Kf,g: X\to G/K 为从闭连通可定向流形 XX 到可定向陪集空间 M=G/KM=G/K 的映射,其中 GG 为紧连通李群,KK 为闭子群,且 dimX=dimM\dim X=\dim M。本文证明:若 L(f,g)=0L(f,g)=0N(f,g)=0N(f,g)=0;若 L(f,g)0L(f,g)\ne 0N(f,g)=R(f,g)N(f,g)=R(f,g),其中 L(f,g)L(f,g)N(f,g)N(f,g)R(f,g)R(f,g) 分别表示 ffgg 的 Lefschetz、Nielsen 与 Reidemeister 重合数。当 dimX>dimM\dim X> \dim M 时,我们给出使 N(f,g)=0N(f,g)=0 蕴含 ffgg 可形变为无重合的条件。
