利用2一余循环对原有Hopf拟群的结构进行代数形变,进而构造出新的Hopf拟群,并讨论了新构造的Hopf拟群上的余拟三角结构与原有Hopf拟群上的余拟三角结构之间的关系,推广了Hopf代数中的相应结论.
In this paper, we study how the multiplication on a Hopf quasigroup can be modified in such a way that the new multiplication together with the original comultiplication and a suitable antipode gives a new Hopf quasigroup. The relationship between coquasitriangular structure of the new Hopf quasigroup and that of the original Hopf quasigroup is also dis- cussed.
