To prove the non-existence of such a ring, we prove the non-existence of a certain ideal in the group algebra 𝔽2[G], with G an alternating or symmetric group as above. We also give examples of rings with unit groups isomorphic to S1, S2, S3, S4, A1, A2, A3, A4, and A8. ...

摘要: Restrictions are given on the dimensions m and k for which there is a map f: m → k whose Jacobian has rank k in a neighbourhood of a singular point if f is either quadratic or even. The restrictions are shown to be best possible in the quadratic case. DOI: 10.1112/jlms/s2-...

In fact, it is well-known that S2( 2U ∗) admits the decomposition (8.1) S2( 2U∗) = B ⊕ 4U∗. Let 1 ≤ k ≤ n be a given integer. Let S2k be the group of permutations of {1, 2, . . . , 2k}; we denote by sgn τ the signature of an element τ of S2k. ...
重庆教育学院经济贸易系,重庆400067摘要:利用有限群的阶及其度数型的性质对素图连通的对称群S9和S28进行了刻画,得到如下结论:设G为有限群,如果|G|=|H|且D G =D H ,则G是3-重OD-刻画的,其中H=S9或者H=S28.素图;几乎单群;顶点的度数;度数型O152.1A2010-12-28西南大学博士创新基金资助项目 ky2010007 ....
