本文沿着近世代数中关于群论的思维脉络和知识体系,将群论中对群的分类思想推广到超群系统中,解决了M型超群的分类问题。首先定义了子核的概念,然后利用子核在超群上建立等价关系,得到等价类,最后通过陪集分解实現对M超群的分类,同时证明了相关的性质定理。超群的陪集分解,不仅解决了M型超群的分类问题,而且为今后研究超群商集的相关性质奠定了理论基础。

Abstract: In this paper, we mainly study the hypergroup based on operation upgrade proposed by H.S.Wall. Firstly, the concept of subnucleus is defined; then the equivalent relation is established by subnucleus on the hypergroup, and the equivalent class is obtained; finally, the classification problem of the M?蛳hypergroup is solved by coset decomposition.
Keywords: hypergroup; equivalence relation; coset; classification
