We study the properties of suspension maps on co-H- spaces and obtain an equalityabout the ranks of the set(group)of all homotopy classes of suspension maps expressed in Bettinumbers on co-H-spaces.
本文探讨ｃｏ－Ｈ－空间上的同纬映象（ｓｕｓｐｅｎｓｉｏｎ）映射的性质，得到一些结果。
Stable homotopy regular morphism is defined in this paper by using suspension functor.
利用同纬映象函子定义稳定同伦正则态射,并研究了稳定同伦正则态射存在的条件及性质,得到如下结果:若态射f:X→Y有稳定同伦标准分解(g,Z,h),设有A,B及相应的态射i:A→X与p:Y→B,使得gi和ph是稳定同伦等价的,则f:X→Y必为稳定同伦正则态射,且在k-稳定同伦意义下惟一。
