Unextendible Sequences in Finite Abelian Groups
Let G = Cn1 ⊕ . . . ⊕ Cnr be a finite abelian group with r = 1 or 1 < n1| . . . |nr, and let S = (a1, . . . , at) be a sequence of elements in G. We say S is an unextendible sequence if S is a zero-sum free sequence and for any element g ∈ G, the sequence Sg is not zero-sum free any longer. Let L(G) = dlog2 n1e + . . . + dlog2 nre and d∗(G) = ∑r i=1(ni−1), in this paper we prove, among other re...
متن کاملThe Jacobsthal Sequences in Finite Groups
Abstract In this paper, we study the generalized order- Jacobsthal sequences modulo for and the generalized order-k Jacobsthal-Padovan sequence modulo for . Also, we define the generalized order-k Jacobsthal orbit of a k-generator group for and the generalized order-k Jacobsthal-Padovan orbit a k-generator group for . Furthermore, we obtain the lengths of the periods of the generalized order-3 ...
متن کاملDecomposing finite Abelian groups
This paper describes a quantum algorithm for efficiently decomposing finite Abelian groups. Such a decomposition is needed in order to apply the Abelian hidden subgroup algorithm. Such a decomposition (assuming the Generalized Riemann Hypothesis) also leads to an efficient algorithm for computing class numbers (known to be at least as difficult as factoring).
متن کاملFactoring finite abelian groups
It is shown that if in the factorization of a finite cyclic group each factor has either prime power order or order equal to the product of two primes then one factor must be periodic. This is shown to be the best possible result of this type. 2004 Elsevier Inc. All rights reserved.
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...
