ALTERNATING GROUPS AS AUTOMORPHISM GROUPS OF RIEMANN SURFACES

International Journal of Algebra and Computation, 2006
In this work we give pairs of generators (x, y) for the alternating groups An, 5 ≤ n ≤ 19, such that they determine the minimal genus of a Riemann surface on which An acts as the automorphism group. Using these results we prove that A15 is the unique of these groups that is an H*-group, i.e., the groups achieving the upper bound of the order of an ...

A characterization of alternating groups

Algebra and Logic, 2005
Given a set \(I\), denote by \(A(I)\) the alternating group on \(I\), that is the group of all almost identical even permutations of \(I\). If \(|I|=n\) then \(A(I)=A_n\). Let \(|I|>4\) and let \(X\) be the set of all \(3\)-cycles \((i,j,k)\) with \(i,j,k\) distinct elements of \(I\). The set \(X\) is a conjugacy class in \(A(I)\), it generates \(A(I)\)

Induced Representations and Alternating Groups

Canadian Journal of Mathematics, 1964
This paper is based on part of the thesis of one of the authors (5), submitted at the University of Toronto in 1963. In the first part of the paper a result on induced representations (2, 4, 9) is generalized slightly and a number of corollaries are derived.

An Alternative to Group Homes

British Journal of Psychiatry, 1978
SummaryThis paper describes a supported lodgings scheme as an alternative to group homes. It is pointed out that the County Council has a statutory duty to finance supported lodgings and that schizophrenics are ideally suited to such a scheme. Some short-stay, the majority of the ‘new’ non-demented long-stay, and a large number of the ‘old’ long-stay ...

A note on the alternating group network

The Journal of Supercomputing, 2010
The class of alternating group networks was introduced in the late 1990’s as an alternative to the alternating group graphs as interconnection networks. Recently, additional properties for the alternating group networks have been published. In particular, Zhou et al., J.

Markov Ciphers and Alternating Groups

2007
This paper includes some relations between differential cryptanalysis and group theory. The main result is the following: If the one-round functions of an r-round iterated cipher generate the alternating or the symmetric group, then for all corresponding Markov ciphers the chains of differences are irreducible and aperiodic.As an application it will be
