摘　　要：本文讨论了由拓扑空间到实与复射影空间的两个映射存在重合点的判别条件,其代数工具是同伦群,而不是同调群.Let f,g:Z→RP^n(or CP^n)be two maps from a topological space to the n-pro-jective space (real or complex).We study some conditions under which the maps f,gmay have a coincidence point.Different from others,the functors applied in this paperare homotopy group functors,not homology group functors.
