A Note on Abelian Groups
Vijayaraghavan and Chowla [2] have proved the following result. If n = 2 or has no primitive root, then there exist suitable reduced residue systems ft, r», • • • , f » and Si, s2, ■ ■ ■ , Sh, where h=in), such that riSi, r2s2, • • • , r^Sh is also a complete residue system (mod n). Since the numbers of a reduced residue system (mod n) form an abelian group with respect to multiplication, it...
متن کاملon finite a-perfect abelian groups
let $g$ be a group and $a=aut(g)$ be the group of automorphisms of $g$. then the element $[g,alpha]=g^{-1}alpha(g)$ is an autocommutator of $gin g$ and $alphain a$. also, the autocommutator subgroup of g is defined to be $k(g)=langle[g,alpha]|gin g, alphain arangle$, which is a characteristic subgroup of $g$ containing the derived subgroup $g'$ of $g$. a group is defined...
متن کاملOn non-normal non-abelian subgroups of finite groups
In this paper we prove that a finite group $G$ having at most three conjugacy classes of non-normal non-abelian proper subgroups is always solvable except for $Gcong{rm{A_5}}$, which extends Theorem 3.3 in [Some sufficient conditions on the number of non-abelian subgroups of a finite group to be solvable, Acta Math. Sinica (English Series) 27 (2011) 891--896.]. Moreover, we s...
متن کاملA note on terraces for abelian groups
We adapt a construction for R-sequencings to give new terraces for abelian groups. This enables the construction of terraces for all groups of the form Z2×Zt where k ≥ 4 and t > 5 is odd. We also present an extendable terrace for Z2 × Z5. When combined with known results this shows that any abelian counterexample to Bailey’s Conjecture (which asserts that all groups except the elementary abelia...
متن کاملA Note on the Action of ^-groups on Abelian Groups
Let £-group P act faithfully on abelian group A. Then P also acts faithfully on A, the abelian group of all linear complex characters of A. Suppose that all orbits in A under the action of P have size at most pe and that all orbits in A have size at most p1'. If A is a p'group, then a simple application of Corollary 2.4 of [2] yields \p\ ^p2e and | JP| ikp21 ■ On the other hand, if A is not a p...
