| 摘 要： | 给出了CoH-arrow群定理的逆定理,并且定义了H-arrow群,得到与CoH-arrow群对偶的定理.同时证明了若CoH-arrow同伦类有分别由CoH-arrow群乘法与H-arrow群乘法给出的两个群乘法,则这两个乘法相同且是可交换的.

| Abstract: | The converse theorem of the CoH-arrow group theorem is given,and the concept of H-arrow group is defined.Then a theorem dual with that of the CoH-arrow group is obtained.Meanwhile,it is proved that the multiplications on the homotopy classes defined by CoH-arrow group and H-arrow group are the same and commutative. |
