On Restricted Set Addition in Abelian Groups
نویسنده
چکیده
Let A be a set of k elements of an Abelian group G in which the order of the smallest nonzero subgroup is at least 2k − 3. Then the number of different elements of G that can be written in the form a + a′, where a, a′ ∈ A, a 6= a′, is at least 2k − 3, as it has been shown in [12]. Here we give yet another proof of this result.

On component extensions locally compact abelian groups
Let $pounds$ be the category of locally compact abelian groups and $A,Cin pounds$. In this paper, we define component extensions of $A$ by $C$ and show that the set of all component extensions of $A$ by $C$ forms a subgroup of $Ext(C,A)$ whenever $A$ is a connected group. We establish conditions under which the component extensions split and determine LCA groups which are component projective. ...
متن کاملSum-dominant sets and restricted-sum-dominant sets in finite abelian groups
A+A = {ai + aj : ai, aj ∈ A}, A−A = {ai − aj : ai, aj ∈ A}, A +̂A = {ai + aj : ai, aj ∈ A and ai 6= aj} respectively. Here we refer to sets A with |A+A| > |A−A| as sum-dominant (some authors use the term MSTD, for more sums than differences sets). Though the fact that addition is commutative but subtraction usually is not might naively suggest that sum-dominant sets are rare if they exist at all...
متن کاملOn continuous cohomology of locally compact Abelian groups and bilinear maps
Let $A$ be an abelian topological group and $B$ a trivial topological $A$-module. In this paper we define the second bilinear cohomology with a trivial coefficient. We show that every abelian group can be embedded in a central extension of abelian groups with bilinear cocycle. Also we show that in the category of locally compact abelian groups a central extension with a continuous section can b...
متن کاملPairwise non-commuting elements in finite metacyclic $2$-groups and some finite $p$-groups
Let $G$ be a finite group. A subset $X$ of $G$ is a set of pairwise non-commuting elements if any two distinct elements of $X$ do not commute. In this paper we determine the maximum size of these subsets in any finite non-abelian metacyclic $2$-group and in any finite non-abelian $p$-group with an abelian maximal subgroup.
متن کاملRestricted set addition in Abelian groups : results and conjectures par
We present a system of interrelated conjectures which can be considered as restricted addition counterparts of classical theorems due to Kneser, Kemperman, and Scherk. Connections with the theorem of Cauchy-Davenport, conjecture of ErdősHeilbronn, and polynomial method of Alon-Nathanson-Ruzsa are discussed. The paper assumes no expertise from the reader and can serve as an introduction to the s...
