摘 要: 對(duì)H.S.Wall提出基于運(yùn)算提升的超群作了進(jìn)一步的研究:首先定義了子核的概念;然后利用子核在超群上建立等價(jià)關(guān)系,得到等價(jià)類;最后通過陪集分解,解決了M型超群的分類問題。

本文沿著近世代數(shù)中關(guān)于群論的思維脈絡(luò)和知識(shí)體系,將群論中對(duì)群的分類思想推廣到超群系統(tǒng)中,解決了M型超群的分類問題。首先定義了子核的概念,然后利用子核在超群上建立等價(jià)關(guān)系,得到等價(jià)類,最后通過陪集分解實(shí)現(xiàn)對(duì)M超群的分類,同時(shí)證明了相關(guān)的性質(zhì)定理。超群的陪集分解,不僅解決了M型超群的分類問題,而且為今后研究超群商集的相關(guān)性質(zhì)奠定了理論基礎(chǔ)。

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?螄hypergroup is solved by coset decomposition.
Keywords: hypergroup; equivalence relation; coset; classification
