摘要
In this letter we show some properties of the maps on co-H-spaces. Let X and Y be co-H-spaces. By using the homology decompositions on co-H-spaces, we obtain a sufficient condition in which an element [f]∈[X, Y] is of finite order in [X, Y] under the binary operation induced by the co-H-structure on X.
